初学JQuery,写了一个高级检索的动态输入框,如图所示: 

实现的功能:

* 当选择属性下拉框中不同类型(字符串、数字、日期)的属性时,后面弹出不同数量的和不同格式的文本框(字符串弹出一个输入文本框,数字型的弹出两个输入文本框,日期型的弹出两个日期选择控件);

* 单击“添加条件”链接后,下面会增加一行条件输入,可以选择逻辑(与、或、非)、属性。

html部分代码如下:


< div id= "0" class ="row" > 

 < dd >

 <select id = "condition" class= "span2" style = 'width:110px;' > 

 <option value= 'and' >与 </option >
 <option value = 'or'> 或</ option>
 <option value= 'not' >非 </option > 

 </select >

 </dd > 

 < dd >< select id= "attrlist" class= "span2" style = 'width:110px;' >
 <s:iterator value= "equipAttrs" id ="attrs" > 
 <option value= '< s:property value= "#attrs[2]" />' ><s:property value= "#attrs[1]" /></option >

 </s:iterator > 

 </select ></dd >

 < dd> <input id = "rangestart" type= "text" class = "span2 search-query"></ dd> 
 < dd> <div id = "rangeend"> --< input type= "text" class = "span2 search-query" ></div ></dd >
 < dd> <div id = "timerange">< input type= "text" id = "datetimepicker1"> --
 <input type = "text" id= "datetimepicker2" >
 </div ></dd >
 <div id = "clickgroup">

 < dd> <button id = "searchButton" type= "submit" class = "btn"> 搜索</ button></ dd> 
 < dd> <a id = "multiSelect" href= "#"> 添加条件 </a ></dd >

 </div > 
</div > 
< div id= "lastrow" ></div >

JQuery代码:


< script type= "text/javascript" src= "js/jquery-1.7.2.min.js" ></ script >
< script type= "text/javascript" >
//用于动态修改新生成的节点id,便于定位子节点,为其添加事件
var conditionCount=1;

$(document).ready( function(){
 $( "#rangeend").hide();
 $( "#timerange").hide();
 $( "#condition").hide();
 //为初始节点添加事件
 selectClick( "0");
 //日期选择控件参数设置
 $( '#[id*=datetimepicker]').datetimepicker({
 format: 'yyyy-mm-dd',
 todayBtn: true,
 startView:4,
 minView:2,
 maxView:4,
 startView:4,
 todayHighlight: true,
 initialDate: new Date(),
 autoclose: true, 
 }); 
 //为“添加条件”添加事件
 $( "#multiSelect").click( function(event){
 var $nextrow=$( "#0").clone(); //克隆初始节点
 $nextrow.attr( "id",conditionCount); //修改复制的节点id,用于定位子节点
 $( "#lastrow").before($nextrow);
 $( "#"+conditionCount+ " select[id='condition']").show();
 $( "#"+conditionCount+ " input[id='rangestart']").show();
 $( "#"+conditionCount+ " div[id='rangeend']" ).hide();
 $( "#"+conditionCount+ " div[id='timerange']" ).hide();
 $( "#"+conditionCount+ " div[id='clickgroup']" ).hide();
 var $t1=$( "#"+conditionCount+ " div[id='timerange']").children();
 var at=$t1.attr( "id");
 $t1.attr( "id",at+ ""+conditionCount);
 $t1=$t1.next();
 var at1=$t1.attr( "id");
 $t1.attr( "id",at1+ ""+conditionCount);
 //为新插入的节点添加事件 
 selectClick(conditionCount);
 conditionCount++;

 $( '#[id*=datetimepicker]').datetimepicker({
 format: 'yyyy-mm-dd',
 todayBtn: true,
 startView:4,
 minView:2,
 maxView:4,
 startView:4,
 todayHighlight: true,
 initialDate: new Date(),
 autoclose: true, 
 }); 

 });
});


 function selectClick(flag){
 /* 三个对象如果放在这里定义的话会出错,每个选择事件都会控制最下面一行的文本框的显示,如果在下面三个事件中分别添加这三行,则事件触发正常 
 $start=$("div[id="+flag+"]>dd>input[id='rangestart']");
 $end=$("div[id="+flag+"]>dd>div[id='rangeend']");
 $time=$("div[id="+flag+"]>dd>div[id='timerange']"); */
 $( "#"+flag+ ">dd>select[id='attrlist']>option[value*='Date']" ).click( function(){
 $start=$( "div[id="+flag+ "]>dd>input[id='rangestart']" );
 $end=$( "div[id="+flag+ "]>dd>div[id='rangeend']" );
 $time=$( "div[id="+flag+ "]>dd>div[id='timerange']" );
 $start.hide();
 $end.hide();
 $time.show();
 });
 $( "#"+flag+ ">dd>select[id='attrlist']>option[value*='String']" ).click( function(){
 $start=$( "div[id="+flag+ "]>dd>input[id='rangestart']" );
 $end=$( "div[id="+flag+ "]>dd>div[id='rangeend']" );
 $time=$( "div[id="+flag+ "]>dd>div[id='timerange']" );
 $start.show();
 $end.hide();
 $time.hide();
 });
 $( "#"+flag+ ">dd>select[id='attrlist']>option[value*='Float']" ).click( function(){
 $start=$( "div[id="+flag+ "]>dd>input[id='rangestart']" );
 $end=$( "div[id="+flag+ "]>dd>div[id='rangeend']" );
 $time=$( "div[id="+flag+ "]>dd>div[id='timerange']" );
 $start.show();
 $end.show();
 $time.hide();
 });
 }
