Question

I want to remove a string that is between two characters, let’s say for example I want to replace all characters of the string between "value=" and " " with "" so value will always equal “”;

Example:

"<input value=98 name=anything>"

To this

"<input value= name=anything>"

How could I do it in JavaScript?

Answer 1

You could probably use regular expressions here, if the structure of the HTML is always like this.

But it would get more complicated if you had to consider value=foo, value="foo" or value="foo bar" too.

Here is a more exciting way, which would work with any kind of HTML string and value:

var tmp_ = document.createElement('div');
tmp_.innerHTML = htmlString;
tmp_.children[0].setAttribute('value', '');

htmlString = tmp_.innerHTML;
