直接上代码

	function disabledinput(){
	
		if($("#input1").attr("disabled") == "disabled"){
			$("#input1").removeAttr("disabled");
		}else{
			$("#input1").attr("disabled","disabled");
		}
		console.log($("#input1").val());
	}
	
	function readonly(){
		var readonly = $('#input2').attr('readonly');
		console.log("readonly:"+readonly);
		if(readonly == "readonly"){
			$('#input2').removeAttr("readonly");
		}else{
			$('#input2').attr('readonly','readonly');
		}
		console.log($("#input2").val());
	}
