Your question is impossible to understand, please be clear. Are you trying to design a web page having checkboxes (for what purpose)? If so, how is Javascript involved?

I mean I need not have to explicityly have to click on the check box, to select it.

better example;

u have a certain multiple choice question on ur webpage and chkboxes to mark the answers.
now i want to select the particular checkbox by entering javascript in the adress bar(ie i write the javascript wher we type the url)
and the appropriate checkbox gets selected.

thst the best I can Explain.

thank you.

Cannot imagine how that would be possible! You should check the box with a mouse click, or use the tab key to move to the check box (if you haven't got a mouse) and then check it using the space bar or so. Is this, by the way, a LinuxQuestions topic?

This almost works in FF and works even less well in IE when I tried it (but it does sort of work):

Code:

javascript:document.getElementById('checkbox').checked=true;

try it and see if it works for you.

But if you want to pass variables to a page through a GET request (in the URL) then you're going to need to use some kind of server-side language (like PHP) to output the correct Javascript code to your webpage. Or better yet, just have it write out the checkbox data with the value="checked" option.

Code:

<html>
<head>
<script language="Javascript">
function checkIt()
{
  document.getElementById("check").click();
}
</script>
</head>
<body>
<input type="checkbox" name="check" id="check" value="Checkbox">
<input type="button" value="Check it!" onClick=checkIt()>
</body>
</html>

Works on Firefox 1.5.

Awesome. Works from the address bar too.

Here is a more general solution, then when it loads the page, it will be clicked if the address is like, http://www.somesite.com/page/asdf.html?checkthebox=1

Code:

<script>
window.location.href.match(/(^[^\?]+\?)(.*)$/);

params = RegExp.$2.split(/\&/);
for(var i = 0; i < params.length; i++) {
	var tmp = params[i].split(/\=/);
	params[i] = [tmp[0], tmp[1]];
}

for(var i = 0; i < params.length; i++) {
	if(params[i][0] == "checkthebox" && params[i][1] == "1")
		document.getElementById('checkbox').checked=true;

}
</script>
