You will want to use DOM-compliant methodologies. This generalized function should help. The third parameter is an inline object of the form
Code:
{parameter_name:'parameter_value', ...}
Where parameter_name is intentionally
not quoted (though, it
may be, if desired) and the value
is quoted. The colon between them is
required.
Separated by a comma, you can add as many as you want.
HTML Code:
<html>
<head>
<script>
function addElement(tag_type, target, parameters) {
//Create element
var newElement = document.createElement(tag_type);
//Add parameters
if (typeof parameters != 'undefined') {
for (parameter_name in parameters) {
newElement.setAttribute(parameter_name, parameters[parameter_name]);
}
}
//Append element to target
document.getElementById(target).appendChild(newElement);
}
</script>
</head>
<body>
<div id="targetTag"></div>
<input type="button" onClick="addElement('INPUT','targetTag',{id:'my_input_tag', name:'my_input_tag', type:'text', size:'5'}); return false;" value="Add Input Tag" />
<input type="button" onClick="addElement('INPUT','targetTag'); return false;" value="Add Input Tag W/O Parameters" />
</body>
</html>
EDIT: One note. If you bother to check the DOM after executing this in IE, you'll see that the name field is not available to you. IE declares this field to be read-only which is why you don't see it. The field will be properly submitted, however, as shown in this test code:
PHP Code:
<?php
if (isset($_POST)) {
print '<pre>'.print_r($_POST,true).'</pre>';
}
?>
<html>
<head>
<script>
function addElement(tag_type, target, parameters) {
//Create element
var newElement = document.createElement(tag_type);
//Add parameters
if (typeof parameters != 'undefined') {
for (parameter_name in parameters) {
newElement.setAttribute(parameter_name, parameters[parameter_name]);
}
}
//Append element to target
document.getElementById(target).appendChild(newElement);
}
</script>
</head>
<body>
<form method="post">
<div id="targetTag"></div>
<input type="submit" value="Check"/>
</form>
<input type="button" onClick="addElement('INPUT','targetTag',{'id':'my_input_tag', 'name':'my_input_tag', 'type':'text', 'size':'5'}); return false;" value="Add Input Tag" />
<input type="button" onClick="addElement('INPUT','targetTag'); return false;" value="Add Input Tag W/O Parameters" />
</body>
</html>
