  • How to call split(token) on a string that does not contain the token without causing an error?

    - by Vorinowsky
    I have two types of strings as the IDs of elements in my HTML markup: Dates: "april-23" "march-20" and season names: "springtime" "winter" The dates have a dash separating the month and the day. The seasons are a single word with no other tokens. I want to assign the month or the season to a new variable called: time_of_year If I do this: var time_of_year = $(this).attr("id").split('-')[0]; It will work on the months but if I call it on a season name which does not contain the token, will it generate an error? What's the safe way to do this?

  • Why does setting document.domain require me to set it in all popups and iframes too?

    - by Chris
    I'm using a long-polling iframe solution for a chat script. Unfortunately, this requires me to set document.domain='yourdomain.com' in the iframe and main document, because the iframe is a subdomain call. The huge problem is...now all my other scripts that use popups and iframes are broken. They now require me to put document.domain in them too. It does fix it, but this is not an ideal solution at all. Is there another way around this problem?

    - by user1574860
    I am using Knockout plugin. The following is my code. In this i am making getting the ceremony list from the server and then save that list in the array. But the problem is in IniitialCallForCeremonies(). The array is not initializing with the returned array from IniitialCallForCeremonies() function. function CeremonyViewModel() { var self = this; self.Ceremonies = ko.observableArray(InitialCallForCeremonies()); } $(document).ready(function () { ko.applyBindings(new CeremonyViewModel()); }); function InitialCallForCeremonies() { var request = $.ajax({ url: "address", type: "GET", async: false, dataType: "JSON" }).success(function (data) { var tempArray = new Array(); $.each(data, function (index, value) { tempArray.push(new Ceremony(value)); }); return tempArray; }); } function Ceremony(val) { this.Id = val.Id; this.Event = val.Event; this.Date = val.Date; this.Guest = val.Guest; }

  • focusout not triggering when clicking on another selector with a click

    - by Sean
    I have 2 divs that each have clicks bound to them. when you click on a div a form is displayed (in another div) that allows you to set properties specific to the div that is clicked. I'm using focusout to save the properties to a data object. everything is working perfectly except when i click on the other div. it seems that the click handler on the other div cancels out the focusout of the form field. Has anyone else experienced this? is so what is the proper way to overcome this?

  • Alert user when they hit the browser back button - with good reson

    - by Dirty Bird Design
    I know this borders on the taboo here, and please don't reply with "you should never do this etc" I have a very long form in a wizard, some users are too used to using the browsers back and forward buttons that they use those instead of the "Back" and "Next" buttons on the form wizard. If they hit the browsers back button they lose all of their form data which is a pain in the ass, since form is so long. Is it possible to display an alert that when will have a "take me out of here" and a "cancel" button so if they hit cancel it will cancel the function of the back button? Thanks!

    I have this function that I am trying to work with. All I am trying to do is to get the values of days, hours, min and sec into the .overTime div. I want to use the same function over and over again because i have more divs in which I want to display the same values but in a diff manner. You guys are awesome Thank You. NowTime = new Date(); //Time Now StartTime = new Date($('#StartTime').val()); StopTime = new Date($('#StopTime').val()); function fixIntegers(integer){ if (integer < 0) integer = 0; if (integer < 10) return '0' + integer; return '' + integer; } function Test( difference ) { var toReturn = { days: 0, hours: 0, minutes: 0, seconds: 0 }; toReturn.seconds = fixIntegers(difference % 60); difference = Math.floor(difference / 60); toReturn.minutes = fixIntegers(difference % 60); difference = Math.floor(difference / 60); toReturn.hours = fixIntegers(difference % 24); difference = Math.floor(difference / 24); toReturn.days = fixIntegers(difference); return toReturn; } function run() { var output = Test( Math.floor( ( NowTime - StopTime ) / 1000 ) ); $('.OverTime').html( output.days + ':' + output.hours + ':' + output.minutes + ':' + seconds); } setInterval(run, 1000) FIDDLE: http://jsfiddle.net/8943U/47/

    $(document).ready(function () { $('#keywordframe').contents().find("#step12").html(''); $('#keywordframe').contents().find("#step12").html('11'); $('#keywordframe').contents().find("#step13").html(''); $('#keywordframe').contents().find("#step13").html('12'); $('#keywordframe').contents().find("#step14").html(''); $('#keywordframe').contents().find("#step14").html('13'); $('#keywordframe').contents().find("#step15").html(''); $('#keywordframe').contents().find("#step15").html('14'); }); I try to use the above code to change the content in an iframe, but it is not working.

  • onKeypress Enter Key event on textfield not working in Chrome

    - by rlcrews
    I have a question along the same vein as the one asked here regarding how the enter key is handled in chrome. The effect I am trying to accomplish is to allow the enter key to call a click event of one a button while focus in within the current field. To accomplish this I am using the following code: javascript: <script type="text/javascript"> //attempting to capture keypress for chrome here but this is not working $("#txtContainer").keypress(function (e) { if (e.keyCode == '13') { e.preventDefault(); doClick(buttonname, e); return false; } }); function doClick(buttonName, e) { var key; if (window.event) key = window.event.keyCode; //IE else key = e.which; //firefox if (key == 13) { var btn = document.getElementById(buttonName); if (btn != null) { btn.click(); event.keyCode = 0 } } } </script> within the aspx <form id="form1" runat="server"> <div> <asp:LinkButton ID="newBtn" runat="server" OnClick="btnLogin_Click" Text="ASP Link" /> <asp:TextBox ID="txtContainer" runat="server" Width="100" /> <asp:Label ID="time_lbl" runat="server" /> </div> </form> and within the code behind aspx.cs protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { txtContainer.Attributes.Add("onKeyPress", "doClick('" + newBtn.ClientID + "',event)"); } } public void btnLogin_Click(object sender, EventArgs e) { time_lbl.Text = txtContainer.Text; } The above code works fine in FF and IE however chrome continues to submit the entire form vs. capturing the keypress on the enterkey. Thank you for any suggestions.

  • How do I show the selected item in an HTML <select> at the top

    - by Michael Meadows
    I have an HTML select that looks something like this (values are fake) <select size="40"> <option value="1">What would you do if I sang out of tune,</option> <option value="2">Would you stand up and walk out on me?</option> ... more <option value="156">Lend me your ears, and I'll sing you a song,</option> <option selected="selected" value="157">I will try not to sing out of key.</option> <option value="158">Oh, I get by with a little help from my friends.</option> ... more <option value="507">I get high with a little help from my friends.</option> <option value="509">Gonna' try with a little from my friends.</option> </select> The problem that I have is that when displaying the list after loading the page and the selected option is in the middle of the very long list, IE scrolls the selected option to the top of the list (which is what I want). Firefox, Chrome, Opera, and Safari show it at the bottom (which I don't want). I have to assume that IE is doing it wrong since everyone else shows it at the bottom. How can I force the browsers to display the selected item at the top of the list. I do not want to put it at the top of the list, I just want it to scroll such that the selected option is at the top. bonus, it would be even better if I can put it fourth from the top, but I can live without that if it's too difficult.

  • What is the proper way to wait a script loaded completely before another

    - by FatDogMark
    I am making a website that is divided by several sections <div id='section-1' class='section'>web content</div> <div id='section-2' class='section'>web content</div> I have like ten sections on my webpage ,each sections height is set to the user window height when document is ready by javascript $('.section').height($(window).height()); Some effects like slideshows on my webpage require the calculated height of the section in order to work properly. Therefore I always use something like this at document ready as a solution. setTimeout(startslideshow,1000); setTimeout(startanimations,1000); ...etc To make sure the section height is the user window height before the slideshow's code start because the sections cannot change to user window height instantly once the webpage loaded will generate serious problems in my slideshow code,like wrong calculated positions. Therefore there will be a situation that's after the page loaded, there will be about a second everything is messed up,before everything can works properly, how could I avoid that being seen by the user? I tried to $(document).hide(),or $('html,body').hide(), then fade in after a second,but I get other weird problems, especially on ipad,my fixed position top navigation bar will always become 'not fixed' while user is scrolling. As I am a self-learner, I afraid my method is not typical. I want to know what is the common ways of real web programmers usually do when they have to divide his webpage into different sections and set its height to window height , then make sure the other effects that's depends on the section height works properly and avoid to wait the height change for a second?

My question is that when the image is replaced, how do I disable the onclick event onclick="return plusbutton();?

  • How to make this JavaScript much faster?

    - by Ralph
    Still trying to answer this question, and I think I finally found a solution, but it runs too slow. var $div = $('<div>') .css({ 'border': '1px solid red', 'position': 'absolute', 'z-index': '65535' }) .appendTo('body'); $('body *').live('mousemove', function(e) { var topElement = null; $('body *').each(function() { if(this == $div[0]) return true; var $elem = $(this); var pos = $elem.offset(); var width = $elem.width(); var height = $elem.height(); if(e.pageX > pos.left && e.pageY > pos.top && e.pageX < (pos.left + width) && e.pageY < (pos.top + height)) { var zIndex = document.defaultView.getComputedStyle(this, null).getPropertyValue('z-index'); if(zIndex == 'auto') zIndex = $elem.parents().length; if(topElement == null || zIndex > topElement.zIndex) { topElement = { 'node': $elem, 'zIndex': zIndex }; } } }); if(topElement != null ) { var $elem = topElement.node; $div.offset($elem.offset()).width($elem.width()).height($elem.height()); } }); It basically loops through all the elements on the page and finds the top-most element beneath the cursor. Is there maybe some way I could use a quad-tree or something and segment the page so the loop runs faster?
