    - by Yuval A
    Suppose you have some <div>s: <div id="div_num1"></div> <div id="div_num2"></div> <div id="div_num3"></div> You can select all those divs by choosing $("div[id^='div_num']"). How can you buld a function that references the number succeeding the prefix? For example, a function which will alert the number 3 for "div_num3". More generally, how can you use full-blown regex in jQuery selectors?

  • Cannot move ckeditor 4 selection to beginning

    - by Gary Hillerson
    I've been exploring numerous solutions in stackoverflow and elsewhere to try to get ckeditor 4 to scroll to the top after I've programmatically added a number of pages to it, using CKEditor's InsertHtml function. After adding my html, which looks fine, I want to position the cursor at the beginning. Here's one of a variety of things I've tried without success: function MoveCaretToStart(myEditor) { var range = new CKEDITOR.dom.range( editor.document ); range.selectNodeContents(editor.document.getBody()); range.moveToElementEditStart(range.root); // also tried range.collapse(true); range.select(); } ... MoveCaretToStart(CKEDITOR.instances['myEditor']); // which already has contents in it This doesn't throw any errors, but also doesn't move the cursor position (it remains at the end of the doc). I thought this one would be easy, but it sure hasn't been. Any help appreciated.

  • XPath conditional text node selection

    - by Reinderien
    Hi there. I need to construct an xpath string to select all descendants of a certain table with these conditions: The table is a descendant of a form with a specific action attribute value. The selected descendants are text nodes. The text node content can only contain whitespace. It'll probably look something like: //form[@action = "submit.html"]//table//text()[ ...? ] Any tips would be appreciated. Thanks. Edit: For clarity, here is my current (working) compromise: function KillTextNodes(rootpath) { XPathIterate(rootpath + '//text()', function(node) { var tagname = node.parentNode.tagName; if (tagname != 'OPTION' && tagname != 'TH') Kill(node); }); }

  • [Android] Show default selection color for custom listview

    - by Diego
    Hello, I have a listview with a custom BaseAdapter. Each row of the listview has a TextView and a CheckBox. The problem is when I click (or touch) any row, the textview foreground becomes gray, instead of the default behavior (background - green, textview foreground - white). Here is the code: row.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" style="@style/layout"> <TextView android:id="@+id/main_lv_item_textView" style="@style/textViewBig" android:layout_alignParentLeft="true"/> <CheckBox android:id="@+id/main_lv_item_checkBox" style="@style/checkBox" android:layout_width="wrap_content" android:layout_alignParentRight="true"/> </RelativeLayout> Custom Adapter: public class CustomAdapter extends BaseAdapter { private List<Profile> profiles; private LayoutInflater inflater; private TextView tvName; private CheckBox cbEnabled; public CustomAdapter(List<Profile> profiles) { this.profiles = profiles; inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public int getCount() { return profiles.size(); } public Object getItem(int position) { return profiles.get(position); } public long getItemId(int position) { return position; } public View getView(final int position, View convertView, ViewGroup parent) { View row = inflater.inflate(R.layout.main_lv_item, null); final Profile profile = profiles.get(position); tvName = (TextView) row.findViewById(R.id.main_lv_item_textView); registerForContextMenu(tvName); cbEnabled = (CheckBox) row.findViewById(R.id.main_lv_item_checkBox); tvName.setText(profile.getName()); if (profile.isEnabled()) { cbEnabled.setChecked(true); } tvName.setOnClickListener(new OnClickListener() { public void onClick(View v) { Bundle bundle = new Bundle(); bundle.putString(PROFILE_NAME_KEY, profile.getName()); Intent intent = new Intent(context, GuiProfile.class); intent.putExtras(bundle); startActivity(intent); } }); tvName.setOnLongClickListener(new OnLongClickListener() { public boolean onLongClick(View v) { selectedProfileName = ((TextView) v).getText().toString(); return false; } }); cbEnabled.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (!profile.isEnabled()) { for (Profile profile : profiles) { if (profile.isEnabled()) { profile.setEnabled(false); Database.getInstance().storeProfile(profile); } } } profile.setEnabled(isChecked); Database.getInstance().storeProfile(profile); updateListView(); } }); return row; } } Any help would be appreciated.

Is there a way of selecting the correct node from those values?

  • Need help displaying a table dynamically based on a drop down date selection

    - by Gideon
    I am designing a job rota planner for a company and need help displaying a dynamic table containing the staff details. I have the following tables in MySQL database: Staff, Event, and Job. The staff table holds staff details (staffed, name, address...etc), the Event table (eventide, eventName, Fromdate, Todate...etc) and the Job table holds (Jobid, Jobdate, Eventid(fk), Staffid (fk)). I need to dynamically display the available staff list from the staff table when the user selects the event and the date (3 drop downs: date, month, and year) from a PHP form. I need to display staff members that have not been assigned work on the selected date by checking the Jobdate in the Job table. I have been at this for all day and can't get around it. I am still learning PHP and would surely appreciate any help I can get. My current code displays all staff members when an event is selected: //Create the day pull-down menu. $days = range (1, 31); echo "<Select Name=day Value=''><Option>Day</option>"; foreach ($days as $value) { echo '<option value="'.$value.'">'.$value.'</option>\n'; } echo "</Select>"; echo "</td><td>"; //Create the month pull-down menu echo "<Select Name=month Value=''><Option>Month</option>"; echo "<option value='01'>Jan</option>"; echo "<option value='02'>Feb</option>"; echo "<option value='03'>Mar</option>"; echo "<option value='04'>Apr</option>"; echo "<option value='05'>May</option>"; echo "<option value='06'>Jun</option>"; echo "<option value='07'>Jul</option>"; echo "<option value='08'>Aug</option>"; echo "<option value='09'>Sep</option>"; echo "<option value='10'>Oct</option>"; echo "<option value='11'>Nov</option>"; echo "<option value='12'>Dec</option>"; echo "</select>"; echo "</td><td>"; //Create the year pull-down menu $currentYear = date ("Y"); $years = range ($currentYear, 2020); echo "<Select Name=year Value=''><Option>Year</option>"; foreach ($years as $value) { echo '<option value="'.$value.'">'.$value.'</option>\n'; } echo "</Select>"; echo "</td></tr></table>"; echo "</td><td>"; //echo "<img src='../ETMSimages/etms_staff.png'</img></td><td>"; //construct the available staff list $staffsql = "SELECT StaffId, LastName, FirstName FROM Staff order by StaffId"; $staffResult = mysql_query($staffsql); if ($staffResult){ echo "<p><table cellspacing='1' cellpadding='3'>"; echo "<th colspan=6>List of Available Staff</th>"; echo "</tr><tr><th> Select</th><th>Id</th><th></th><th>Last Name </th><th></th><th>First Name </th></tr>"; while ($staffarray = mysql_fetch_array($staffResult)) { echo "<tr onMouseOver= this.bgColor = 'red' onMouseOut =this.bgColor = 'white' bgcolor= '#FFFFFF'> <td align=center><input type='checkbox' name='selectbox[]' id='selectbox[]' value=".$staffarray['StaffId']."> </td><td align=left>".$staffarray['StaffId']." </td><td>&nbsp&nbsp</td><td align=center>".$staffarray['LastName']." </td><td>&nbsp&nbsp</td><td align=center>".$staffarray['FirstName']." </td></tr>"; } echo "</table>"; } else { echo "<br> The Staff list can not be displayed!"; } echo "</td></tr>"; echo "<tr><td></td>"; echo "<td align=center><input type='submit' name='Submit' value='Assign Staff'>&nbsp&nbsp"; echo "<input type='reset' value='Start Over'>"; echo "</td></tr>"; echo "</table>";

  • HTML Double Click Selection Oddity

    - by Aren B
    I didn't post this on DocType because it's not really a design thing, the visual representation isn't my problem, the behaviour is. I'm sorry if this is misplaced but I don't feel it's a designer issue. The following DOM: <ul style="overflow: hidden;"> <li style="float: left;"><strong>SKU:</strong>123123</li> <li style="float: left;"><strong>ILC:</strong>asdasdasdasd</li> </ul> Or <div style="overflow: hidden;"> <div style="float: left; width: 49%"><strong>SKU:</strong>123123</div> <div style="margin-left: 50%; width: auto;"><strong>ILC:</strong>asdasdasdasd</div> </div> Or <p> <span><strong>SKU:</strong>123123</span> <span><strong>ILC:</strong>asdasdasdasd</span> </p> All present me an odd problem in IE 6 IE 7 Firefox 3.x Chrome But not in IE 8 When you double click '123123' after 'SKU:', it selects '123123' AND 'ILC:' from the next dom element. Take any text on this page (here in SO), double click a word, it only selects THAT WORD, even in the middle of a paragraph. These examples have dom elements closing them, anyone know why this is happening. My fellow employees use the 'double click' mechanism to select the relevant product ID's to do their job, and this dosen't make sense to me what soever.

"); while ($row = $db->sql_fetchrow($result)) { //fetching other $vars ---- $tags_id = explode(" ",$row['tags']); $c = count($tags_id); for($i=1;$i<$c-1;$i++){ list($tag_name,$slug) = $db->sql_fetchrow($db->sql_query( 'SELECT `tag`,`slug` FROM `bt_tags` WHERE `tid` = "'.tags_id[$i].'"

  • Winform datagridview selection is wrong after editing.

    - by jparram
    I am using a winform datagridview. The datagridviews datasource is a binding source. The gridview is using the CellEndEdit event to update the datasource. The datasource gets updated and the follwing property is set: public List<Collection> Collections { set { this.SubjectCollectionDOBindingSource.DataSource = value; } } If I end the cell editing with the 'enter' key, all works as expected. If I end the edit by clicking another cell, the data is updated as expeceted but subsequent clicks on cell columns do not correspond with the highlighted cell: ie the highlighted cell is the previously clicked cell. What steps are considered best practice when updating a gridview so that when all is said and done it is in the desired state?

  • Jquery autosuggest google maps - Load on selection

    - by user1738522
    At the moment, the Google map code works like this: When you start typing in the input box it loads a list of suggestions. Then when you click on one of these options from the list, it puts it into the input box. However, THEN you still have to click find to load up the result. I want to have it so when you click on an option from the autosuggest list, it automatically loads the result, without having to click "find" afterwards. This is the code I am working with. I hope I explained this question correctly. http://jsfiddle.net/BxG9H/

  • Change style of text field based on the selection of a combo box using Javascript

    - by baldwingrand
    I would like to change the style of a text field based on the value selected in a combo box. Specifically, what I'd like to do is make the txtDepartment field gray and marked as "read only" if the option value selected in cboSource is 1. I've tried the code below, but I imagine my style code at least is wrong, if not other things. Any help appreciated. Thanks! <select name="cboSource" id="cboSource" onClick="displayDepartment(this);"> <option value = 1>Source 1</option> <option value = 2>Source 2</option> </select> <input name="txtDepartment" type="text" id="txtDepartment" size="6" maxlength="6"></p> <script> function displayDepartment(obj) { var selectedValue = obj.value; var txtDepartment = document.getElementById("txtDepartment"); if (selectedValue == "1") { txtDepartment.style.display = "Disabled style='background-color:#E8E8E8'"; } } </script>

    Is there a way to prevent an annotation in a MKMapView instance from being enabled. In other words, when the user taps the red pin on the map, is there a way to prevent it from highlighting the pin. Right now the pin turns dark when touched... Edit: I'm using the following code to return the MKPinAnnotationView // To future MKMapView users - Don't forget to set _mapView's delegate _mapView.delegate = self; _annotation = [[MKPointAnnotation alloc] init]; _annotation.coordinate = myLocation; [_mapView addAnnotation:_annotation]; -(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{ MKPinAnnotationView *pin = [[MKPinAnnotationView alloc] initWithAnnotation:_annotation reuseIdentifier:@"id"]; pin.enabled = NO; return pin; }
