Question

Onclick javascript events not working in all but IE

Asked by: resourcesys

Hi there,
I am doing some work on a website and am having some problems getting onclick events working with anything other than IE. The website is written in vbscript, Asp and use some javascript.
I am working on a website search feature that consists of a text box and an image that acts as a button.

I have included two snippets of code to show how I am trying to fire the onclick events.
The first is an input textbox that blanks out some default text when clicked.

The second is an image that sends back a variable to tell a script that it is to search for some particular text.

In IE both work perfectly. The blanking of the textbox does not work in anything other than IE.

However in Safari, a search can be initialised by hitting 'return'.
Any help would be great.

regards,
Peter

<input name="chr_SearchTerm" value="<%=xchr_SearchTerm%>" type="text" class="SearchBox" id="Text1" onclick="BlankSearchbox()" />
 
<img src="images/inf_whitesearch.gif" alt="search button" width="30" height="26" align="absmiddle" style="cursor:hand" 
 onClick="javascript:this.document.frmMain.xchr_FrmAction.value='search';submit()"/>

Yeah :D

I had the same trouble once and one of my genius developer friends showed me the way. IE does not pay any attention *on its own* to OnClick events. The only way to do it will be very costly, but it will work on all browsers

You will have to re-write your JS to handle the browser and attach the right-way-for-the-right-browser.

Hello,

Try using onfocus="BlankSearchbox()"  for the textbox .

For the image, change onClick to onclick, I have seen cases when that causes issues. Then this.document.frmMain.xchr_FrmAction.value='search' seems to set the value of a control with the name of xchr_FrmAction in the form named frmMain to the word 'search'; after that it calls the submit() function.

First, we can get rid of this. as document. is getting the page element anyway, then let's make sure the items being used all have names and not just ids being called in the command. Lastly if the function submit() is defined in the header or external .js name it something else, as it is a call in javascript that needs an object to be called on. Otherwise, if you meant to submit the form mentioned in the previous command, use: document.frmMain.submit().

Also this coed should help:

<html>
<head>
<script type="text/javascript">
	function test1(){
		document.getElementById("txtBox").value = "";
}
	function test2(){
		alert("form has been submitted");
}
</script>
</head>
 
 
<body>
 
 
<form name="myform" onsubmit="test2()" action="" method="">
	<input type="text" value="random" id="txtBox" name="txtBox" onfocus="test1()"  />
	<input type="image" alt="Submit" src="" />
 
</form>
</body>
</html>

or...

<html>
	<head>
		<script type="text/javascript">
			function doSomething()
			{
				document.frmMain.xchr_FrmAction.value='search';
				alert("text value changed!");
				document.frmMain.submit();
			}
			function BlankSearchbox()
			{
				document.frmMain.chr_SearchTerm.value='';
			}

	</head>

Thank you all for your help.
document.frmMain.submit() sorted the problem.
Also I was using name instead of id with document.getElementById.

thanks again.
