jquery ui中的dialog

博客分类：

JQuery

dialog jquery ui

听说jquery ui中dialog和easy ui中的dialog很像，因为没有用过easy ui，但在工作中有用到jquery ui中dialog，于是从官网上将例子看了下，并记录如下。

实例一

这是一个很简单的应用，打开一个对话框。

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="jquery-ui.css">
  <script src="jquery-1.10.2.js"></script>
  <script src="jquery-ui.js"></script>
  <link rel="stylesheet" href="style.css">
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>
</head>
<body>

<div id="dialog" title="Basic dialog">
  <p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>

</body>
</html>

代码$( "#dialog" ).dialog();加载页面的时候弹出一个对话框。效果如下：

实例二

点击按钮，弹出带动画功能的对话框，定义显示和影藏效果，effect: "blind"：打开时时百叶窗效果，从上到下显示，effect: "explode"关闭时是爆发，碎片效果。

这里不是页面加载的时候就显示对话框，而是点击添加账号的时候弹出这个对话框，所以要先定义这个对话框“$( "#dialog" ).dialog({,”，点击添加按钮的时候弹出对话框“dialog.dialog( "open" );”。

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>jQuery UI Dialog - Animation</title>
  <link rel="stylesheet" href="jquery-ui.css">
  <script src="jquery-1.10.2.js"></script>
  <script src="jquery-ui.js"></script>
  <link rel="stylesheet" href="style.css">
  <script>
  $(function() {
    $( "#dialog" ).dialog({
      autoOpen: false,
      show: {
        effect: "blind",
        duration: 1000
      },
      hide: {
        effect: "explode",
        duration: 1000
      }
    });
 
    $( "#opener" ).click(function() {
      $( "#dialog" ).dialog( "open" );
    });
  });
  </script>
</head>
<body>
 
<div id="dialog" title="Basic dialog">
  <p>This is an animated dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>
 
<button id="opener">Open Dialog</button>

</body>
</html>

作用是弹出一个模态确认对话框，mode:true，不能操作后面的父页面，除非关闭当前的对话框。在对话框上加了两个按钮，一个确认，一个取消，可以分别做一些操作，其实也不限于这两个按钮，如果需要的话可以在下面添加任意多个按钮，实现任意多的功能。

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>jQuery UI Dialog - Modal confirmation</title>
  <link rel="stylesheet" href="jquery-ui.css">
  <script src="jquery-1.10.2.js"></script>
  <script src="jquery-ui.js"></script>
  <link rel="stylesheet" href="style.css">
  <script>
  $(function() {
    $( "#dialog-confirm" ).dialog({
      resizable: false,
      height:140,
      modal: true,
      buttons: {
        "Delete all items": function() {
          $( this ).dialog( "close" );
        },
        Cancel: function() {
          $( this ).dialog( "close" );
        }
      }
    });
  });
  </script>
</head>
<body>
 
<div id="dialog-confirm" title="Empty the recycle bin?">
  <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered. Are you sure?</p>
</div>
 
<p>Sed vel diam id libero <a href="http://example.com">rutrum convallis</a>. Donec aliquet leo vel magna. Phasellus rhoncus faucibus ante. Etiam bibendum, enim faucibus aliquet rhoncus, arcu felis ultricies neque, sit amet auctor elit eros a lectus.</p>

</body>
</html>

带form功能的对话框，这个例子有些复杂，可以实现验证，请求等功能。

<!doctype html>

    label, input { display:block; }
    input.text { margin-bottom:12px; width:95%; padding: .4em; }
    fieldset { padding:0; border:0; margin-top:25px; }
    h1 { font-size: 1.2em; margin: .6em 0; }
    div#users-contain { width: 350px; margin: 20px 0; }
    div#users-contain table { margin: 1em 0; border-collapse: collapse; width: 100%; }
    div#users-contain table td, div#users-contain table th { border: 1px solid #eee; padding: .6em 10px; text-align: left; }

      tips = $( ".validateTips" );
 
    function updateTips( t ) {
      tips

      },
      close: function() {

        allFields.removeClass( "ui-state-error" );
      }
    });
 
    form = dialog.find( "form" ).on( "submit", function( event ) {

运行效果：

点击添加用户弹出对话框

元素验证失败时

这个带请求功能的对话框，代码很严谨，例子很经典！

var dialog, form,
emailRegex = /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/,
name = $( "#name" ),
email = $( "#email" ),
password = $( "#password" ),
allFields = $( [] ).add( name ).add( email ).add( password ),
tips = $( ".validateTips" );

定义元素变量，要用到的验证，allFields = $( [] ).add( name ).add( email ).add( password ),这个用来把要用到的变量加到集合里面，用来添加和删除css样式，后面会用到的，很巧妙，$( [] )这个写法可以把多个元素添加到一个集合中。

function updateTips( t ) {
      tips
        .text( t )
        .addClass( "ui-state-highlight" );
      setTimeout(function() {
        tips.removeClass( "ui-state-highlight", 1500 );
      }, 500 );
}

给元素添加文字和css样式，并且在500毫秒内移除这个样式。

function checkLength( o, n, min, max ) {
      if ( o.val().length > max || o.val().length < min ) {
        o.addClass( "ui-state-error" );
        updateTips( "Length of " + n + " must be between " +
          min + " and " + max + "." );
        return false;
      } else {
        return true;
      }
}

检查输入文字的长短，4个参数分别是元素本身，元素名称，最小长度，最大长度。

function checkRegexp( o, regexp, n ) {
      if ( !( regexp.test( o.val() ) ) ) {
        o.addClass( "ui-state-error" );
        updateTips( n );
        return false;
      } else {
        return true;
      }
}

用正则表达式检查元素是否符合规则，3个参数，元素本身，正则表达式，错误提示。

function addUser() {
      var valid = true;
      allFields.removeClass( "ui-state-error" );
 
      valid = valid && checkLength( name, "username", 3, 16 );
      valid = valid && checkLength( email, "email", 6, 80 );
      valid = valid && checkLength( password, "password", 5, 16 );
 
      valid = valid && checkRegexp( name, /^[a-z]([0-9a-z_\s])+$/i, "Username may consist of a-z, 0-9, underscores, spaces and must begin with a letter." );
      valid = valid && checkRegexp( email, emailRegex, "eg. ui@jquery.com" );
      valid = valid && checkRegexp( password, /^([0-9a-zA-Z])+$/, "Password field only allow : a-z 0-9" );
 
      if ( valid ) {
        $( "#users tbody" ).append( "<tr>" +
          "<td>" + name.val() + "</td>" +
          "<td>" + email.val() + "</td>" +
          "<td>" + password.val() + "</td>" +
        "</tr>" );
        dialog.dialog( "close" );
      }
      return valid;
}

添加用户的方法，验证方法valid = valid && 这个用的很巧妙，连续利用了&&操作，这里的写法非常的灵活也很巧妙。在这里可以实现具体的功能，也可以在form里面添加action，form到具体页面中操作。

dialog = $( "#dialog-form" ).dialog({
      autoOpen: false,
      height: 300,
      width: 350,
      modal: true,
      buttons: {
        "Create an account": addUser,
        Cancel: function() {
          dialog.dialog( "close" );
        }
      },
      close: function() {
        form[ 0 ].reset();
        allFields.removeClass( "ui-state-error" );
      }
});

这里是最主要的功能，一个定义一个对话框，其中有个2个按钮，一个是添加一个账号，访问addUser函数，一个是取消，直接定义关闭对话框，最后还定义了默认的关闭功能，form中清除元素的值，清除错误提示。

form = dialog.find( "form" ).on( "submit", function( event ) {
      event.preventDefault();
      addUser();
});

定义form，其实就是页面中的form，还定义了提交时请求动作，首先取消默认事件，然后执行addUser。

$( "#create-user" ).button().on( "click", function() {
      dialog.dialog( "open" );
});

给添加用户按钮绑定事件，这里绑定事件没有直接.click，也没有live，也没有trigger，on是jquery官方推荐的一个绑定函数方法。注意这里不是页面加载的时候就显示对话框，而是点击添加账号的时候弹出这个对话框，所以要先定义这个对话框“dialog = $( "#dialog-form" ).dialog({”，点击添加按钮的时候弹出对话框“dialog.dialog( "open" );”。

实例五

模态对话框，作用是弹出一个模态对话框，mode:true，其实就是后面不能回到后面的父页面，除非关闭当前的对话框。在对话框后面加了一个OK关闭按钮。
