初學JQuery，寫了一個高級檢索的動態(tài)輸入框，如圖所示：
實現(xiàn)的功能：
* 當選擇屬性下拉框中不同類型（字符串、數(shù)字、日期）的屬性時，后面彈出不同數(shù)量的和不同格式的文本框（字符串彈出一個輸入文本框，數(shù)字型的彈出兩個輸入文本框，日期型的彈出兩個日期選擇控件）；
* 單擊“添加條件”鏈接后，下面會增加一行條件輸入，可以選擇邏輯（與、或、非）、屬性。
html部分代碼如下：
< div id= "0" class ="row" > < dd > <select id = "condition" class= "span2" style = 'width:110px;' > <option value= 'and' >與 </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= "#"> 添加條件 </a ></dd > </div > </div > < div id= "lastrow" ></div >
JQuery代碼：
