I'm currently using a YUI gadget. I also do have a Javascript function to validate the output that comes from the div that YUI draws for me:
Event.on("addGadgetUrl", "click", function(){
var url = Dom.get("gadget_url").value; /* line x ------>*/
if (url == "") {
error.innerHTML = "<p> error" /></p>";
} else {
/* line y ---> */
/* I need to add some code in here to set the value of "gadget_url" by "" */
}
}, null, true);
Here is my div:
<div>
<p>URL</p>
<input type="text" name="gadget_url" id="gadget_url" style="width: 350px;" class="input"/>
<input type="button" id="addGadgetUrl" value="add gadget"/>
<br>
<span id="error"></span>
</div>
As you can see my question is, how can I set the value of gadget_url to be ""?
