Hi All; I have this javascript which is adding a new button to the column in the row which is created dynamically, the innerhtml shows that the onclick event is correctly added but it never gets invoked when I click it. newcol = doc.createElement("TD"); newbutton = doc.createElement("input"); newbutton.name = "newChange"+__uid;

I am curious if there is a benefit to set attributes directly, in my javascript, or to use setAttribute. For example, I have this: var input = document.createElementNS(xhtmlNS, 'input'); input.setAttribute('width', '20em'); I could have just called input.width='20em' When is each better to use, or is there no difference between them?

Hi, I am working on a web application which among other things uses DHTML, Java and Javascript. It populates web page based on the contents of the database (resultset), and next to each row there is a checkbox (v1) allowing to select that row for changes (e.g. delete, update, etc.) So we are creating an array of checkbox, correct ? Of...

Is there any wildcard, like *, for addressing all the element ID's on the page at once, like if you want to hide all layers at once. For example: document.getElementById('*').style.visibility = 'hidden'; I know the above doesn't work but you get what I'm driving at right? Is there anything like that for that method or in javascript in...

However, if the first object on a screen is a radiobutton it will not accept focus...

Hi, Normally, a piece of code such as <a href="http://www.yahoo.com" onclick="alert('hello');return false;">link</a> will stop the browser from actually going to href's destination. However, this is not the case with the IE7 I am using. What has changed?

I know of course that you can use <script src=""></script> in an HTML document to include javascript code you don't want to spill all over the page.
