• IE7 and IE8 change event not being thrown for text input

  - by Sam

  I have a form that I auto focus at startup of the page with jquery. I also have change event handlers in place for whenever an input changes. If I change the value of the first field that was autofocused, and then move to the next field, the change event handler doesn't fire. If I remove the autofocusing, and just focus manually, then change it then move to the next field, the change event does fire. This only happens on IE. It works fine on firefox and chrome. Anyone experience this before?

• html open a url on new target and focus.

  - by richard

  I am trying to fix a web site. It opens a help page in a new window/tab via <a href="..." target="help"> (no other frame has this name) This works well the first time opening a new window/tab, for the help. But on subsequent clicks the window/tab is loaded but remains hidden. I tryed this: <script> function OpenAndFocusHelp() { win=window.open('help/1000CH00017.htm','help'); win.focus(); } </script> <a href="help.html" target="help" onclick="OpenAndFocusHelp()">Help</a> It did not work!

So my question is, how do I get this input to happen?

• jQuery see if next element (not sibling) exists

  - by DevlshOne

  Here's my HTML code: <select class="grid_3 required jobData valid" id="clli" name="clli" style="font-size: 10px; border: none;"> <option value="0">Select One...</option> <option value="905"></option> <option value="931">0</option> <option value="1">ABRDMSES</option> </select> <img alt="This data has been changed!" title="This data has been changed!" src="images/caution.png"> <img alt="This data has been changed!" title="This data has been changed!" src="images/caution.png"> <img alt="This data has been changed!" title="This data has been changed!" src="images/caution.png"> <select class="grid_3 required jobData" id="job_status" name="job_status" style="font-size: 10px; border: none;"> <option value="0">Select One...</option> </select> When a $('#clli').change(); occurs, I slap a caution image next to it to warn the user that there are changes to be saved. However, if they make more than one change to the same element, I first want to see if there is already a caution image there before sending a new one. Any theories/methods on how to just scope out the next (but not $.next()) element?

• What is the best way to observe the scroll over an element with overflow set?

  - by Phunky

  It's simple to observe the documents scroll event but I can't seem to find anything relating to the scroll of any other element with css property overflow being set? To get around this myself i've been observing mousemove which only fires while you hold down on the scrollbar but this would need to be teamed with a mouse wheel observe also to get the full effect. Could anyone point me in the right direction for a better way of implementing this?

• Loop through array, print with string.

  - by Adam

  I have a simple array like: var myArr=["one","two","three"]; an I have a counting loop, which increases the value of var i by one. What I want to do is print the next value from the array each time the loop runs, next to a text string, like so: alert('value number '+myArr[i]+); But for some reason I can't get this to work. The following code works, so I'm assuming I'm not calling the counter right: alert('value number '+myArr[0]+);
