Capturing event when User right-click->paste into text box

[RBPierce]

Hey all, hoping someone can help me with a workaround. I've got an event set to fire when a textbox changes or loses focus- no problems. However, when the user clicks into the box and Right Click--> Pastes a value into it, I can't get any event to fire. I've tried onClick, OnChange, OnMouseDown, onMouseUp, onKeyDown, and onKeyUp.

<input type='text' onChange="alert('Changed')" onClick="alert('Clicked')" onMouseDown="alert('onMouseDown')" onMouseUp="alert('onMouseUp')" onKeyDown="alert('onKeyDown')" onKeyUp="alert('onKeyUp')">

I know I can do one of those stupid IE named scripts, but I was hoping someone somewhere had a multi-browser compliant solution!

Heya, RB. Welcome to TSDN!

Changed thread title to better describe the problem (did you know that threads whose titles do not follow the Posting Guidelines actually get FEWER responses?).

Please use CODE tags when posting source code. See the REPLY GUIDELINES on the right side of the page next time you post.

Welcome to TSDN!

Unfortunately, there's no reliable cross-browser way to capture a paste event. You can check this thread out. Why is it so important to capture this? Can you not just wait for onchange to fire when the text box loses focus?

Thanks PB!

acoder, upon successfully completing the input field in question, that value is then used to auto-complete various other fields on the page. If the user has to wait until they have tabbed/clicked to another input box in order for the auto-completion to kick in, we have violated GUI best practices by separating cause and effect.

Additionally, I have helper text in which prompts the user what is needed, i.e. "Start Date required". That text disappears after a valid date is entered... unless they mouse paste, in which case the text remains, while they can clearly see that a good date WAS entered.

Anyway, thanks for the help!

you can write a timer to check the value of the so called input box

Example provided.

<script>
var ival = "";
var checkup = window.setInterval("checkChange();", 100);
function checkChange() {
var nval = document.getElementById("test").value;
if (nval!=ival) { alert("change in the text"); ival=nval; }
}
</script>
<input type="text" id="test" name="test" value="">

Aah, that makes more sense. Well, iam_clint has posted a good workaround. Hopefully that should solve your problem.

Thanks iam- I'll look into it!

I wonder if you can use an onclick or maybe onrightclick (?) event handler that compares the current value of the textbox to the last value....

[EDIT: Just about the same thing iam_clint posted, except without the setInterval() call. Ah well.]

Thanx ....
this was really helpful...

we can call the same function used to capture rest of mouse and key events(onkeyup,onblurr etc) .


this is wat i did for a multiline textbox to change the height dynamically

<asp:TextBox ID="txtdemo" runat="server" TextMode="MultiLine" Width="286px" onmouseup = "fnStartClock()" onkeydown="textAreaSize()" onblur="textAreaSize()" onfocus="textAreaSize()" onkeyup="textAreaSize()" height="16px" ></asp:TextBox>

////////////////////////////////////////////////////
function used for any event after clicking the mouse button called for a particular interval(for onmouseup and onmousedown)
///////////////////////////////////////////////////
var oInterval;
function fnStartClock(){
if(oInterval!=null)
{
 window.clearTimeout(oInterval);
 i=0;
 }
   oInterval = window.setInterval("textAreaSize()", 200); 
 
}
 
//////////////////////////////////////////////////
here textAreaSize() is the function called for the rest of the events....
it is used to change the height of a multiline textbox on entering a data 
/////////////////////////////////////////////////
var i=0;
 
function textAreaSize()
{
 
var na= document.getElementById('ctl00_BodyContent_txtdemo')
 
var text = na.value.replace(/\s+$/g,'') ;  
var split = text.split("\n");  
var tbHeight = 16*split.length; 
if(tbHeight>200)
tbHeight=200
   document.getElementById('ctl00_BodyContent_txtdemo").style.height = tbHeight;
 i++;
 if(i>100)
 {
 window.clearTimeout(oInterval);
 i=0;
 }
 
}

hope this is helpful.....

Thanks Clint, that was very helpful.
