is there a simple way to use javascript replace to remove contents inside tags

Question

there is long string, like

<td>sdfaf</td><td width='1'></td><td width='1'>sdfdsf</td><td></td>

Is there a simple regex method to delete contents inside tags, convert it to

<td></td><td width='1'></td><td width='1'></td><td></td>

I know jquery html() and empty() can do the work, but I want to find a pure javascript method to do it.

thanks

I see you use the tag regex so I guess you thought it could be a good idea to try to use a regex to remove HTML content. I'll just let you read this. — Denys Séguret

Assuming your "string" comes from a table in your document, here's how to do it in vanilla javascript :

var cells = yourtable.getElementsByTagName('td');
for (var i=0; i<cells.length; i++) cells[i].innerHTML = '';

(if you just have the string, you may simply create a tr node and set this string as innerHTML)

try this simple code

var tds = document.getElementsByTagName("td");

for ( var counter = 0; counter < tds.length; counter++ )
{
  tds[ counter ].innerHTML = ""; 
}

Rough and ready, assuming no angle brackets between or inside the tags:

 str = str.replace( />[^<]+<\//g, '></' );

@user995789. Why have you accepted an answer that doesn't "use javascript replace" and which is not a "simple regex method"? Is it because of the high rep of the person that answered?
