Help me with this function

**d9esco** · 02-01-2016, 01:41 AM

I have a variable that stores the value of a search box. This value is supposed to represent the id of another element. I want to use the focus command in javascript to focust on the value as an id in the page. how do I do this? This is what I had.

Code:

function search(){
			var val = document.getElementById('search').value;
			val.focus();
			}

Code:

	<body id="body" onload="document.getElementById('title').focus();">
	


	<input value="  Search" id="search" onclick="document.getElementById('search').value=' '"></input>
	
	<button id="button" onclick="search();">Search</button>

Trim extra whitespace first, and then getElementById

Code:

function trim(str) {
     return str.replace(/^\s+|\s+$/g, '');
     }

function search(){
     var val = document.getElementById('search').value;
     val = trim(val);
     document.getElementById(val).focus();
     }
