Use jQuery's attr method to modify the onclick value_jquery

Okay, let’s just paste the js code for everyone

var js = "alert('B:' + this.id); return false;"; 
var newclick = eval("(function(){"+js+"});"); 
$("#anchor").attr('onclick', '').click(newclick);

If the onclick event originally had a value, it must be cleared first and then assigned using click( eval(function(){.....}) )

$("input[name='orderCar']").attr('onclick','').click( eval(function(){Test()})); 

function Test(){ 
alert("测试通过！"); 
return; 
}

If I can help you, please step on me hard down there.
