本文,將使用validate.js驗證插件功能,完成表單註冊驗證的功能。javascript
1、html部分css
html部分幾乎不須要更改太多,只要加個存放錯誤提示的列表標籤便可。html
<ol class="reg_error"></ol>
index.html:前端
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>知問前端</title> <script type="text/javascript" src="jquery-1.12.3.js"></script> <script type="text/javascript" src="jquery-ui.js"></script> <script type="text/javascript" src="jquery.validate.js"></script> <script type="text/javascript" src="index.js"></script> <link rel="shortcut icon" type="image/x-icon" href="img/favicon.ico" /> <link rel="stylesheet" type="text/css" href="jquery-ui.css" /> <link rel="stylesheet" type="text/css" href="style.css" /> </head> <body> <div id="header"> <div class="header_main"> <h1>知問</h1> <div class="header_search"> <input type="text" name="search" class="search" /> </div> <div class="header_button"> <button id="search_button">查詢</button> </div> <div class="header_member"> <a href="###" id="reg_a">註冊</a> | <a href="###" id="login_a">登陸</a> </div> </div> </div> <form id="reg" action="123.html" title="會員註冊"> <ol class="reg_error"></ol> <p> <label for="user">帳號:</label> <input type="text" name="user" class="text" id="user"></input> <span class="star">*</span> </p> <p> <label for="pass">密碼:</label> <input type="password" name="pass" class="text" id="pass"></input> <span class="star">*</span> </p> <p> <label for="email">郵箱:</label> <input type="text" name="email" class="text" id="email"></input> <span class="star">*</span> </p> <p> <label>性別:</label> <input type="radio" name="sex" id="male" value="male" checked="checked"><label for="male">男</label></input> <input type="radio" name="sex" id="female" value="female"><label for="female">女</label></input> </p> <p> <label for="date">生日:</label> <input type="text" name="date" readonly="readonly" class="text" id="date"></input> </p> </form> </body> </html>
2、css部分java
css部分主要是成功後引入一張小圖標,還有錯誤列表樣式。jquery
#reg .star { font-size: 14px; color: maroon; /* 紅色太耀眼,換成棕色 */ } #reg .succ { display: inline-block; /* 將<span>元素(內聯)轉變成內聯塊,並且<span>裏還要有數據,插入的圖片才能顯示出來 */ width: 28px; background: url(img/reg_succ.png) no-repeat; } #reg ol { margin:0; padding: 0 0 0 20px; color: maroon; } #reg ol li { height: 20px; }
style.css:app
body { margin: 40px 0 0 0; padding: 0; font-size: 12px; font-family: 宋體; background: #fff; } /* 更改jQuery UI主題的對話框header的背景 */ .ui-widget-header { background: url(img/ui_header_bg.png); } /* 按鈕正常狀態的背景 */ .ui-state-default, .ui-widget-content .ui-state-default, .ui-widget-header .ui-state-default { background:url(img/ui_header_bg.png); } /* 按鈕點擊狀態的背景 */ .ui-state-active, .ui-widget-content .ui-state-active, .ui-widget-header .ui-state-active { background:url(img/ui_white.png); } /* 工具提示的文本顏色 */ .ui-tooltip { color: #666; } /* 郵箱自動補全的懸停背景色 */ .ui-menu .ui-state-focus { background:url(img/ui_header_bg.png); } .ui-menu { color: #666; } /* 日曆UI的今天單元格樣式 */ .ui-datepicker-today .ui-state-highlight { border:1px solid #eee; color:#f60; } /* 日曆UI的選定單元格樣式 */ .ui-datepicker-current-day .ui-state-active { border:1px solid #eee; color:#06f; } .a { font-size: 30px; } #header { width: 100%; height: 40px; background: url(img/header_bg.png); position: absolute; top:0; } #header .header_main { width: 800px; height: 40px; margin: 0 auto; } #header .header_main h1 { font-size: 20px; margin: 0; padding: 0; color: #666; line-height: 40px; float: left; padding: 0 10px; } #header .header_search { padding: 6px 0 0 0; float: left; } #header .header_search .search { width: 300px; height: 24px; border: 1px solid #ccc; background: #fff; color: #666; font-size: 14px; text-indent: 5px; } #header .header_button { padding: 5px; float: left; } #header .header_member { float: right; line-height: 40px; color: #555; font-size: 14px; } #header .header_member a { text-decoration: none; font-size: 14px; color: #555; } #reg { padding: 15px 0 0 15px; } #reg p { margin: 10px 0; padding: 0; } #reg p label { font-size: 14px; color: #666; } #reg .star { font-size: 14px; color: maroon; /* 紅色太耀眼,換成棕色 */ } #reg .succ { display: inline-block; /* 將<span>元素(內聯)轉變成內聯塊,並且<span>裏還要有數據,插入的圖片才能顯示出來 */ width: 28px; background: url(img/reg_succ.png) no-repeat; } #reg ol { margin:0; padding: 0 0 0 20px; color: maroon; } #reg ol li { height: 20px; } #reg .text { border-radius: 4px; border: 1px solid #ccc; background: #fff; width: 200px; height: 25px; line-height: 25px; text-indent: 5px; font-size: 13px; color: #666; }
3、jQuery部分ide
jQuery部分很常規,基本使用了validate.js的核心功能。工具
index.js:ui
$(function() { $("#search_button").button({ icons:{ primary:"ui-icon-search", }, }); //$("#reg").dailog(...)返回的是jQuery對象,即對話框內容的div(id="reg")對象,因此能夠連綴使用 $("#reg").dialog({ autoOpen:true, modal:true, resizable:false, width:320, height:340, buttons:{ '提交':function() { $(this).submit(); } } }).buttonset().validate({ submitHandler:function(form) { alert("驗證成功,準備提交中!"); }, //錯誤提示出現,對話框高度增長,出現滾動條,因此應去除滾動條 //每次激活錯誤,都會觸發此屬性 showErrors:function(errorMap, errorList) { var errors = this.numberOfInvalids(); if(errors > 0) { $("#reg").dialog("option","height",errors * 20 + 340); } else { $("#reg").dialog("option","height",340); } this.defaultShowErrors(); //執行默認錯誤 }, //高亮顯示有錯誤的元素,變色式 highlight:function(element,errorClass) { $(element).css("border","1px solid #630"); }, //恢復默認 unhighlight:function(element,errorClass) { $(element).css("border","1px solid #ccc"); //element即爲<input>控件 //$(element).parent().find("span").html("ok"); $(element).parent().find("span").html(" ").addClass("succ"); }, errorLabelContainer:"ol.reg_error", wrapper:"li", rules:{ user:{ required:true, minlength:2 }, pass:{ required:true, minlength:6 }, email:{ required:true, email:true }, date:{ date:true } }, messages:{ user:{ required:"帳號不得爲空!", minlength:"帳號不得小於{0}位!" }, pass:{ required:"密碼不得爲空!", minlength:"密碼不得小於{0}位!" }, email:{ required:"郵箱不得爲空!", email:"請輸入正確的郵箱地址!" } } }); $("#date").datepicker({ changeMonth:true, changeYear:true, yearSuffix: ' ', maxDate:0, yearRange:"1950:2020", }); $("#email").autocomplete({ delay:0, autoFocus:true, source:function(request,response) { var hosts = ['qq.com','163.com','126.com','sina.com.cn','gmail.com','hotmail.com'], term = request.term, //獲取用戶輸入的內容 name = term, //郵箱的用戶名,如i_beautiful host = '', //郵箱的域名,如sina.com.cn ix = term.indexOf('@'), //@的位置 result = []; //最終呈現的郵箱列表 result.push(term); if(ix > -1) { name = term.slice(0, ix); host = term.slice(ix + 1); } if(name) { var findedHosts = (host ? $.grep(hosts, function(value, index) { return value.indexOf(host) > -1; }) : hosts), findedResult = $.map(findedHosts, function(value, index) { return name + "@" + value; }); result = result.concat(findedResult); } response(result); } }); });
