use*_*301 6 html javascript jquery
我想在$("#address").change函数内部执行警报,但只有在使用按钮更改值时才需要执行此操作.
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$('button').click(function(){
$("#address").val("hi")
})
$("#address").change(function(){
alert("The text has been changed.");
});
});
</script>
</head>
<body>
<input type="text" id="address">
<button>Click</button>
</body>
</html>
您可以change在click函数中触发事件:
$('button').click(function(){
$("#address").val("hi")
$("#address").change(); //or $("#address").trigger("change");
});
$("#address").change(function(){
alert("The text has been changed.");
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="address" type="text">
<button>Change</button>
