Bookmarklet to fill forms matched to a regex
We can not use a regex in getElementsByXXX("/^like this*/").
So we have to get superset of what we need and then evaluate each element whether its name (or tagname or something) matches to the regex.
Example
<form> <input type="text" name="target0" value="target0" /> <input type="text" name="target1" value="target1" /> <input type="text" name="dummy0" value="dummy0" /> <input type="text" name="target2" value="target2" /> <input type="text" name="target3" value="target3" /> <input type="text" name="dummy1" value="dummy1" /> </form> <button id="changebtn">change</button> <script> document.getElementById("changebtn").onclick = function(){ var es = document.getElementsByTagName("input"); for( var i=0; i<es.length; i++ ){ var e = es[i]; if( e.name.match(/^target.*/) ) { e.value = "changed!"; /*somehow necessary for scriptlet on my environment*/ console.log(); } } } </script>
How to register the script as a bookmarklet
- Show bookmark-toolbar (Ctrl-Shift-b)
- Rclick -> Add page...
- URL : javascript:{ [PASTE THE SCRIPT IN A LINE] }
