jquery高亮关键字

$(function() {
		if("${orderIndexs}" != "") {
			setTimeout(highLight(), 1000);
		}
	});
	function highLight() {
		$("#companyListTable tr td").each(function() {
			var words = "${orderIndexs}".split(" ");
			for(var i=0; i<(words.length); i++) {
				var keyword = words[i];
				var reg = new RegExp(keyword,"ig");//它是对字符串执行模式匹配:i,大小写;g,全局匹配
				var str = $(this).html().replace(reg,"<font style='background-color:#FFFF69'>"+keyword+"</font>");
				$(this).html(str);				
			}			
		});
	}
