禁止输入

JS

window.onload = function(){
	var _inhibitingInput = document.getElementById("inhibitingInput");
	//第一种写法  控制失去焦点
	_inhibitingInput.onfocus = function(){
		_inhibitingInput.blur();
	}

	//第二中写法 通过keyup 与blur 组合使用
	/* 		var noText = function (){
	 _inhibitingInput.value = "";
	 }

	 _inhibitingInput.onkeyup =
	 _inhibitingInput.onblur = noText; */
};
