根据指定内容选中复选框

JS

window.onload = function(){
	var contentCheckbox = document.getElementById("contentCheckbox"),
			_targets = document.getElementsByName(contentCheckbox.getAttribute("data-target")),
			targetsLen = _targets.length,
			i = 0;
	contentCheckbox.onkeyup = function(){
		for(i = 0 ; i < targetsLen ; i ++){
			var _t = _targets[i],
					_v = this.value;
			//如果内容与复选框的关键词匹配，选择当前的复选框
			//三元运算写法
			/*_v.search(_t.getAttribute("data-k")) != -1 ?
			 _t.checked = true :
			 _t.checked = false;*/

			//单链式条件写法
			_t.checked = _v.search(_t.getAttribute("data-k")) != -1 && true || false;
		}
	}
};
