jQuery对表单表格的操作及更多应用
一、下拉框应用
选中左边选项添加到右边 ，选中右边添加到左边
<script type="text/javascript"> $(function(){ $("#add").click(function(){ var $option=$("#select1 option:selected"); $option.appendTo("#select2");//appendTo可以完成先删除后追加 }) $("#add_all").click(function(){ var $option=$("#select1 option"); $option.appendTo("#select2"); }) $("#select1").dblclick(function(){//双击事件绑定 var $option=$("option:selected",this);//获取选中的选项 $option.appendTo("#select2"); }) $("#remove").click(function(){ var $option=$("#select2 option:selected"); $option.appendTo("#select1"); }) $("#remove_all").click(function(){ var $option=$("#select2 option"); $option.appendTo("#select1"); }) $("#select2").dblclick(function(){ var $option=$("option:selected",this); $option.appendTo("#select1"); }) }) </script>
<style type="text/css"> .centent{ float:left; margin-right:50px;} span{ display:block;} </style>
</head>
<body>
<div class="centent">
<select multiple="multiple" id="select1" style="width:100px;height:100px;">
<option value="1">选项1</option>
<option value="2">选项2</option>
<option value="3">选项3</option>
<option value="4">选项4</option>
<option value="5">选项5</option>
<option value="6">选项6</option>
<option value="7">选项7</option>
<option value="8">选项8</option>
</select>
<div>
<span id="add">选中添加到右边>></span>
<span id="add_all">全部添加到右边>></span>
</div>
</div>
<div class="centent">
<select multiple="multiple" id="select2" style="width:100px;height:100px;">
</select>
<div>
<span id="remove"><<选中删除到左边</span>
<span id="remove_all"><<全部删除到左边</span>
</div>
</div>
</body>二、表格展开关闭与内容筛选
完整表格
表格折叠
表格内容筛选
<script type="text/javascript"> $(function(){ $('tr.parent').click(function(){ $(this) .toggleClass("selected")//添加/删除高亮 .siblings('.child_'+this.id).toggle();//隐藏/显示子行 }) $("#filterName").keyup(function(e) { //输入内容，搜索相应结果，隐藏其他内容，只显示搜索内容 $("table tbody tr").hide().filter(":contains('"+($(this).val())+"')").show(); }).keyup();//DOM加载完后，绑定事件完成后立即触发，表格内容保持刚才筛选出来的结果 }) </script>
<style type="text/css"> .selected{ color:#5B5A5A;} </style>
</head>
<body>
搜索：<input type="text" id="filterName">
<table>
<thead>
<tr><th>姓名</th><th>性别</th><th>暂住地</th></tr>
</thead>
<tbody>
<tr class="parent" id="row_01"><td colspan="3">前台设计组</td></tr>
<tr class="child_row_01"><td>张山</td><td>男</td><td>浙江宁波</td></tr>
<tr class="child_row_01"><td>李四</td><td>女</td><td>浙江杭州</td></tr>
<tr class="parent" id="row_02"><td colspan="3">前台开发组</td></tr>
<tr class="child_row_02"><td>王五</td><td>男</td><td>湖南长沙</td></tr>
<tr class="child_row_02"><td>找六</td><td>男</td><td>浙江温州</td></tr>
<tr class="parent" id="row_03"><td colspan="3">后台开发组</td></tr>
<tr class="child_row_03"><td>Rain</td><td>男</td><td>浙江杭州</td></tr>
<tr class="child_row_03"><td>MAXMAN</td><td>女</td><td>浙江杭州</td></tr>
</tbody>
</table>
</body>三、网页字体大小
放大缩小字体按钮
<script type="text/javascript"> $(function(){ $("span").click(function(){ var thisEle = $("#para").css("font-size"); //获取元素字体大小,返回数值和单位 var textFontSize = parseInt(thisEle , 10);//parseInt去掉了单位，如16px获得16，第二个参数是进制，10进制 var unit = thisEle.slice(-2); //获取单位，slice()返回指定字符开始的一个子字符串，-2从倒数第二位开始，即获得px var cName = $(this).attr("class"); if(cName == "bigger"){ textFontSize += 2; }else if(cName == "smaller"){ textFontSize -= 2; } $("#para").css("font-size", textFontSize + unit ); }); }); </script>
<style type="text/css"> </style>
</head>
<body>
<div class="msg">
<div class="msg_caption">
<span class="bigger" >放大</span>
<span class="smaller" >缩小</span>
</div>
<div>
<p id="para" >
This is some text. This is some text. This is some text. This is some text. This

</body>四、网页选项卡
<script type="text/javascript"> $(function(){ $("div.tab_menu ul li").click(function(){ $(this).addClass("selected") .siblings().removeClass("selected"); var index=$("div.tab_menu ul li").index(this); $("div.tab_box>div").eq(index).show() .siblings().hide(); }) }) $("div.tab_menu ul li").click(function(){ $(this).addClass("selected") .siblings().removeClass("selected"); var index=$("div.tab_menu ul li").index(this); $("div.tab_box >div").eq(index).show() .siblings().hide(); }) </script>
<style type="text/css"> .tab_menu li { float:left; text-align:center; cursor:pointer; list-style:none; padding:1px 6px; margin-right:4px; background:#F1F1F1; border:1px solid #898989; border-bottom:none;} .tab_box{ clear:both; border:solid 1px #6C6A6A; width:300px; height:100px; } .hide{ display:none;} .tab_menu li.hover { background:#DFDFDF;} .tab_menu li.selected { color:#FFF; background:#6D84B4;} </style>
