javascript reg expression to replace value="...

[Rod McLure]

I have this javascript where I am looping thru all the cells in a row from a table,
this row is just a copy of the previous row so i need to set all the value=something to value=""
in my test example value="231" in both the alert statements, ps need to work in IE 8 Thanks to anyone who can assist.

str = table.rows[table.rows.length-1].cells[i].innerHTML;
		if(i==0){
		alert(i+"red alert"+str);
		//removes bean values - from hidden field 0
    		reg = new RegExp('(value=\")[^\"]+(\")', 'g');
    		str = str.replace(reg, 'value=\"\"');

		alert(i+"red alert"+str);
    		}

Why in the world are you doing it through innerHTML and not DOM?

table.rows[table.rows.length-1].cells[i].getElementsByTagName("input")[0].value = "foo";

Where in your code are you getting a reference to the hidden elements? innerHTML is not going to cut it!

P.S. This is where using a library such as jQuery really pays off. Using jQuery, it's a single statement:

$('#tableId input[type="hidden"]').val('');

I did not want to bore you with how I got str,
but now that I have it how to i replace value= with value=""
first alert
---------------------------
0red alert<INPUT id=field-30 value=231 type=hidden name=outcomeId>
---------------------------

second alert

0red alert<INPUT id=field-30 value=231 type=hidden name=outcomeId>
---------------------------
OK
---------------------------

Doing it with innerHTML is still the wrong way to go on many levels.

Your debug string has no ", but your regular expression is looking for them.

Thank you!,
the script was written in Firefox and the alerts have quotes in them there,
but this will not work in Explorer

[Eric Pascarello]

So make the quotes match zero or one time
