• Extending jQuery Form Validation Script for new form fields

  - by user982124

  I have a simple HTML form that originally was a series of Questions (A1 to A5 and B1 to B3) with yes/no radio buttons like this: <tr> <td width="88%" valign="top" class="field_name_left">A1</td> <td width="12%" valign="top" class="field_data"> <input type="radio" name="CriteriaA1" value="Yes">Yes<input type="radio" name="CriteriaA1" value="No">No</td> </tr> The user could only answer either the A series of questions OR either the B series of questions, but not both. Also they must complete all questions in either the A or B series. I now have an additional series of questions - C1 to C6 - and need to extend my validation scripts to ensure the user enters either A, B or C and answers all questions within each series. My original script for just the A and B looks like this: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A _OR_ B if(isAorB()){ $("#error").html("Please complete A or B, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's if(allAorBChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorB(){ var OK = false; var Achecked = false; var Bchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if (Achecked && Bchecked){ OK = true; } }); return OK; } function allAorBChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }else{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } This worked well but I'm completely stuck at extending it to include the C series. I now have to check that the user hasn't answered any A and B, A and C and B and C questions. Everything I've tried fails to validate. Here's where I'm at right now with my new script: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A or B or C if(isAorBorC()){ $("#error").html("Please complete A or B or C, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's or all C's if(allAorBorCChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorBorC(){ var OK = false; var Achecked = false; var Bchecked = false; var Cchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(theChar == "B" && this.checked && !Achecked){ Bchecked = true; } if(theChar == "C" && this.checked && !Achecked){ Cchecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if(Achecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if(Bchecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if (Achecked && Bchecked){ OK = true; } if (Achecked && CBchecked){ OK = true; } if (Bchecked && Cchecked){ OK = true; } }); return OK; } function allAorBorCChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }elseif{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } }else{ // set the input to C $("#type").val("C"); // check _all_ c's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "C"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } Anyone see what I'm doing wrong?

• asp.net checkbox in gridview - checked property is missing

  - by Peter PitLock

  In this asp.net gridview control, the checked property is always missing. I need to access the checked property via jquery Gridview source: <Columns> <asp:TemplateField> <ItemTemplate> <asp:CheckBox ID="chkSelected" runat="server" class="chkSummarySelection" /> </ItemTemplate> </asp:TemplateField> </Columns> Renders as : <input type="checkbox" name="ctl00$ContentPlaceHolder1$gv$ctl02$SelectedCheckBox" id="ctl00_ContentPlaceHolder1_gv_ctl02_SelectedCheckBox"> There is no checked property to access.

  - by Prasad

  I need to check the checked property of a checkbox and perform an action based on the checked property using jQuery. For example, if the age checkbox is checked, then I need to show a textbox to enter age, else hide the textbox. But the following code returns false by default: if($('#isAgeSelected').attr('checked')) { $("#txtAge").show(); } else { $("#txtAge").hide(); } How do I successfully query the checked property?

• Checking if radio buttons are checked in Firefox

  - by Andrew Song

  On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

• Ubuntu App Submission won't allow the "free" bubble to be checked

  - by Compt

  I am at the final stages of the Ubuntu App Developer Showdown, and I'm right at the point where I am submitting my app. The problem I run in to however, is that even though buy is at $0.00, it will not allow me to click on the "free" button, and keep that configuration saved. So when I go to "preview your app", it shows it saying "USD $0.00 ---- Buy" instead of saying "Free ---- Install". So I was wondering if it makes any difference or not.

• How to deal with checked exceptions that cannot ever be thrown

  - by ammoQ

  Example: foobar = new InputStreamReader(p.getInputStream(), "ISO-8859-1"); Since the encoding is hardcoded and correct, the constructor will never throw the UnsupportedEncodingException declared in the specification (unless the java implementation is broken, in which case I'm lost anyway). Anyway, Java forces me to deal with that exception anyway. Currently, it looks like that try { foobar = new InputStreamReader(p.getInputStream(), "ISO-8859-1"); } catch(UnsupportedEncodingException e) { /* won't ever happen */ } Any ideas how to make it better?

• Git doesn't sync files until committed, even if checked out in a different branch

  - by DertWaiter

  Okay, I have git 1.7.11.1 on Windows and I have a local test repository with 2 branches. One is master with index.php and help.php. I then create another branch called slave :) I run from git bash rm help.php and it disappears from the folder, but I don't stage anything. I switch to checkout master branch and it is supposed to restore file help.php because it is not modified in the master branch, isn't it? And it does not do it. When I go back to the slave branch and commit and then switch to checkout master then help.php appears. Is that the way it is supposed to to work? Why?

• Dynamic Table CheckBoxes not having a "Checked" true value

  - by LuvlyOvipositor

  I have been working on a web app using ASP.NET with the code base as C#. I have a dynamic table that resizes based on a return from a SQL query; with a check box added in the third cell of each row. The checkbox is assigned an ID according to an index and the date. When users hit the submit button, the code is supposed to get a value from each row that is checked. However, when looping through the rows, none of the check boxes ever have a value of true for the Checked property. The ID persists, but the value of the checkbox seems to be lost. Code for adding the Checkboxes: cell = new TableCell(); CheckBox cb = new CheckBox(); cell.ApplyStyle(TS); cb.ID = index.ToString() + " " + lstDate.SelectedItem.Text.ToString(); if (reader["RestartStatus"].ToString() == "0") { cb.Checked = false; cb.Enabled = true; } else { cb.Checked = true; } cell.Controls.Add(cb); The code for getting the checkbox value: for (int i = 0; i < CompTable.Rows.Count; i++) { int t3 = CompTable.Rows[i].Cells[2].Controls.Count; Control temp = null; if (t3 0) { temp = CompTable.Rows[i].Cells[2].Controls[0]; } string t2 = i.ToString() + " " + lstDate.SelectedItem.Text.ToString(); if ( temp != null && ((CheckBox)temp).ID == i.ToString() + " " + lstDate.SelectedItem.Text.ToString()) { //Separated into 2 if statements for debugging purposes //ID is correct, but .Checked is always false (even if all of the boxes are checked) if (((CheckBox)temp).Checked == true) { tlist.Add(CompTable.Rows[i].Cells[0].Text.ToString()); } } }

• Disable a checkbox in javascript and recognize it as checked on the server side

  - by kuzco

  I have a checkbox which in some cases may be disabled and checked using javascript, i.e: var cbTest = document.getElementById("CheckBoxTest"); cbTest.disabled = true; cbTest.checked = true; However, when sending a postback, CheckBoxTest.Checked is false on the server side. Is it possible to disable the checkbox and still have the server side recognize it as checked?

• WinForms (C#) Databinding Object to Checkbox.Checked Property

  - by Trevor Sullivan

  Hello, I'm writing a WinForms app, and am trying to bind a boolean property on a .NET object to a Checkbox's "checked" property. I am successfully creating the binding, but when I change the source property's value from false to true (I have a button that toggles it), the checkbox's "checked" property does not reflect that change. if (chkPreRun.DataBindings["Checked"] == null) { Debug.WriteLine("Adding chkPreRun databinding"); Binding _binding = chkPreRun.DataBindings.Add("Checked", NwmConfig, "PreRun") // Added this just to ensure that these were being set properly _binding.DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged; _binding.ControlUpdateMode = ControlUpdateMode.OnPropertyChanged; } I am able to successfully bind the text property to the value of a TextBox, for example. I'm not sure what I'm missing while binding to the "Checked" property, however. Cheers, Trevor

• Change Check Out Folder for checked out files in SourceSafe

  - by Town

  I had to rebuild my machine and went from XP to Windows 7. I've now got a bit of an issue: I had files checked out in SourceSafe previously, which I still have copies of in the local folder on my new install. However, SourceSafe still has them checked out to the old XP folder (c:\documents and settings etc) whereas the files now reside in c:\Users. Pending Checkins in Visual Studio now thinks I have nothing checked out, and SourceSafe declares that the files are checked out to me under the c:\documents and settings\ path. Is there any way to tell SourceSafe to simply "look over there" for the files instead? It seems to work with individually undoing and redoing checkout on the files, but that's a lengthy process and one I'd like to avoid if possible. If I simply checkout the files individually then it lists them as checked out to me twice, one for each of the locations. Any pointers would be very much appreciated!

• jquery checked checkbox IE problem

  - by lidermin

  Hi, I'm having an issue verifying if a checkbox is checked using jquery on Internet Explorer. This is the code I'm using: if ($('#chkjq_1').attr('checked') == true) It works fine on Firefox or Chrome, but on Internet Explorer 7, the condition is always false because the browser sets the property this way: <input id="chkjq_1" type="checkbox" CHECKED/> IE7 And the right way is the following: (Firefox, Chrome): <input id="chkjq_1" type="checkbox" checked="checked"/> FF, Chrome, etc What should I do to avoid this issue on Internet Explorer 7; is there a generic way in jquery to solve this? Thanks in advance.

• jQuery if checkbox is checked to toggle classes

  - by Lynx

  I am needed to change my jQuery code up. Instead of the label toggling the class and showing the icon I need it to where if the checkbox is checked to show to toggle those classes. I have tried prop and is but I couldn't get them to work properly. The reason for the change is I want to preload data into the form and if it's going to be checked those toggles need to reflect that change. http://jsfiddle.net/70fbLooL/2/ EDIT Seems to be confusion as to exactly what I am trying to do. The fiddle I provided works perfectly fine. The problem is if I want to call the form from server-side and pre-populate the form the checkbox toggles will not show that they are checked because it's based on the clicked function. I need it to be based on if the checkbox equal true or checked. That way if the value equals true from the server-side call it will toggle those classes and look like it's checked.

• building jquery checkbox - can't set checked value

  - by benpage

  this seems straightforward enough, I don't know if it's a bug, or just something I'm doing wrong. What I want to do is build a checkbox input in jquery, then return the string of the input. I have this code: var obj = $('<input>'); obj.attr('disabled', 'disabled'); obj.attr('type', 'checkbox'); obj.attr('checked', 'checked'); // this does not work! no matter how i try to render this obj, the 'checked' attribute never gets outputted. So I have tried: $('<div>').append(obj).remove().html(); and it returns: <input type="checkbox" disabled="disabled" /> I have tried setting an id attribute, it makes no difference. I have also tried this but it doesn't work: obj.attr('checked', true); Any suggestions on how to get the input tag rendered with the checked attribute set to 'checked' (via jquery)? I realise I can just do this with string concatenation, but now I really want to know why it's not working the way it should.

• MVVM-Light EventToCommand Behavior for CheckBox Checked/Unchecked in Silverlight

  - by George Durzi

  I would like to handle the Checked and Unchecked events of a Checkbox control and execute a command in my ViewModel. I wired up an EventTrigger for both the Checked and Unchecked events as follows: <CheckBox x:Name="chkIsExtendedHr" IsChecked="{Binding Schedule.Is24Hour, Mode=TwoWay}"> <i:Interaction.Triggers> <i:EventTrigger EventName="Checked"> <GalaSoft_MvvmLight_Command:EventToCommand CommandParameter="{Binding IsChecked, ElementName=chkIsExtendedHr}" Command="{Binding Path=SetCloseTime, Mode=OneWay}" /> </i:EventTrigger> <i:EventTrigger EventName="Unchecked"> <GalaSoft_MvvmLight_Command:EventToCommand CommandParameter="{Binding IsChecked, ElementName=chkIsExtendedHr}" Command="{Binding Path=SetCloseTime, Mode=OneWay}" /> </i:EventTrigger> </i:Interaction.Triggers> </CheckBox> I defined a RelayCommand in my ViewModel and wired up an action for it: public RelayCommand<Boolean> SetCloseTime{ get; private set; } ... SetCloseTime= new RelayCommand<bool>(ExecuteSetCloseTime); The parameter in the action for the command always resolves to the previous state of the CheckBox, e.g. false when the CheckBox is checked, and true when the CheckBox is unchecked. void ExecuteSetCloseTime(bool isChecked) { if (isChecked) { // do something } } Is this expected behavior? I have a workaround where I have separate triggers (and commands) for the Checked and Unchecked and use a RelayCommand instead of RelayCommand<bool>. Each command executes correctly when the CheckBox is checked and unchecked. Feels a little dirty though - even dirtier than having UI code in my ViewModel :) Thanks

• radiobutton checked on condition in jquery

  I have the following fields: <label>Company Type:</label> <label for="primary"><input onclick="javascript: $('#sec').hide('slow');$('#primary_company').find('option:first').attr('selected','selected');" type="radio" runat="server" name="companyType" id="primary" />Primary</label> <label for="secondary"><input onclick="javascript: $('#sec').show('slow');" type="radio" runat="server" name="companyType" id="secondary" />Secondary</label> <div id="sec"> <fieldset> <label for="primary_company">Primary Company:</label> <%= Html.DropDownList("primary_company", Model.SelectPrimaryCompanies, "** Select Primary Company **") %> </fieldset> If there is a primary_company, then the secondary radio button should be selected. If there is no primary_company, then the primary radio button should be selected. Here is my jQuery: $(document).ready(function() { if ($('#primary_company').val().length > 0) { $('#secondary').attr({ checked: true }); } else { $("#primary").attr('checked', true ); $('#sec').hide(); } The sec div hides and shows properly, but a radio button is never selected. I've tried .attr('checked', 'checked') and .attr({ checked: true }) and .attr('checked', true) but nothing is ever selected.
