模态窗口改为警告 [英] Modal window instead alert
本文介绍了模态窗口改为警告的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我需要修改此脚本，以便在允许的字符数末尾，而不是警告用户可以看到模态警告窗口，在N秒后消失。在这种情况下，光标应该冻结到位并且无法进一步输入。
提前感谢您的建议。
I need to modify this script so that at the end of the allowed number of characters, instead of alert user can see a modal warning window, which disappears after N seconds. In this case, the cursor should freeze in place and further typing is impossible. Thanks in advance for your advice.
这是我的代码：
<!DOCTYPE html>
<html lang="en">
<head>
<title>Textbox</title>
<script type="text/javascript" src="http://ajax.googleapis.com/
ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$("#contentbox").keyup(function()
{
var box=$(this).val();
var main = box.length *100;
var value= (main / 145);
var count= 145 - box.length;
if(box.length <= 145)
{
$('#count').html(count);
$('#bar').animate(
{
"width": value+'%',
}, 1);
}
else
{
alert(' Stop! ');
}
return false;
});
});
</script>
<style>
#barbox
{
float:right!;
height:14px;
background-color:#FFFFFF;
width:100px;
border:solid 2px #000;
margin-right:3px;
margin-bottom:10px;
overflow: inherit;
}
#bar
{
background-color:#ff0000;
width:0px;
height:14px;
}
#count
{
float:right; margin-right:8px;
font-family:'Georgia', Times New Roman, Times, serif;
font-size:16px;
font-weight:bold;
color:#333;
}
#contentbox
{
width:450px; height:50px;
border:solid 2px #006699;
font-family:Arial, Helvetica, sans-serif;
font-size:14px;
}
</style>
</head>
<body>
<div>
<div id="count">145</div>
<div id="barbox"><div id="bar"></div></div>
</div>
<textarea id="contentbox"></textarea>
</body>
</html>

您可以使用jQuery库创建模态对话框：

modal: true,
autoOpen: false,
//set a timeout of 3 secs to close it again, when opened
open: function(event, ui) {
setTimeout("$('#dialog-modal').dialog('close')", 3000);
},
//when closing, make the textarea readonly
close : function(){
