本文介紹了jQuery 實時保存頁面動態添加的數據的示例，分享給大家，具體如下：

需求：用戶填寫的東西，必須要實時保存

分析：監聽用戶操作事件，如：change、keyup 等，向后端發送請求

實際情況：

動態新增代碼：

// template() 是一個模板格式化函數$('#modal_pl_content').html(template('modal_temp', {data:''}));

模板代碼：

<script id="modal_temp" type="text/html"><form class="cksd_comment_id">     <div class="col-sm-12 addID">    <input type="hidden" name="comment_update_id" value="" />       <div class="col-sm-12 hr hr-18 dotted hr-dotted"></div>    <div class="col-sm-3 form-group">              <label class="col-sm-3 control-label no-padding-right">評價ID</label>            <div class="col-sm-9"><input type="text" class="col-xs-12" name="commentID"></div>         </div>         <div class="col-sm-1 form-group">            <select name="star" onchange="checkIsInput(this)">                <option value="5">5</option>                <option value="4">4</option>                <option value="3">3</option>                <option value="2">2</option>                <option value="1">1</option>            </select>         </div>         <div class="col-sm-4 form-group">              <label class="col-sm-3 control-label no-padding-right">當前數量</label>            <div class="col-sm-8">                <div class="col-sm-5"><input type="text" class="col-xs-12" name="now_yes" onkeyup="is_intdata(this,this.value)" value="0"></div>                  <label class="col-sm-1 control-label no-padding-left no-padding-right">of</label>                <div class="col-sm-5"><input type="text" class="col-xs-12" name="now_total" onkeyup="is_intdata(this,this.value)" value="0"></div>            </div>        </div>          <div class="col-sm-3 form-group">              <div class="col-sm-12">                  <label class="col-sm-1 control-label no-padding-left no-padding-right">Yes</label>                  <div class="col-sm-5"><input type="text" class="col-xs-12" name="add_yes" onkeyup="is_intdata(this,this.value)" value="0"></div>                  <label class="col-sm-1 control-label no-padding-left no-padding-right">No</label>                  <div class="col-sm-5"><input type="text" class="col-xs-12" name="add_no" readonly onkeyup="is_intdata(this,this.value)" value="0"></div>      </div>          </div>        <div class="col-sm-1 form-group">總數： <br><span class="total_yes">0</span> of <span class="totals">0</span></div>         <div class="col-sm-1 form-group delbox"><button type="button" class="btn btn-danger btn-xs" onclick="delPlID(this)">刪除</button></div>     </div>  </form></script>
