本文介绍了jQuery 实时保存页面动态添加的数据的示例,分享给大家,具体如下:
需求:用户填写的东西,必须要实时保存
分析:监听用户操作事件,如:change、keyup 等,向后端发送请求
实际情况:
动态新增代码:
// template() 是一个模板格式化函数 $('#modal_pl_content').html(template('modal_temp', {data:''}));
模板代码:
<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">评价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">当前数量</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">总数: <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)">删除</button></div> </div> </form> </script>
事件监听与发送请求代码:
$(document).on("change keyup", ".cksd_comment_id", function(event) { /* var current = event.target.tagName.toLowerCase(); if ((current != 'input') || (current != 'select')) { event.preventDefault(); } */ var praise_row = {}; praise_row.cpid_a = $("[name='cpid_a']").val(); praise_row.pt_a = $("[name='pt_a']").find("option:selected").val(); praise_row.dp_a = $("[name='dp_a']").find("option:selected").val(); praise_row.cptime_start = $("[name='cptime_start']").val(); praise_row.cptime_end = $("[name='cptime_end']").val(); praise_row.cpkeyword_a = $("[name='cpkeyword_a']").val(); praise_row.status = $("[name='cksd_status']").val(); if (praise_row.cpid_a && praise_row.pt_a && praise_row.dp_a && praise_row.cptime_start && praise_row.cptime_end) { var comment_row = {}; $(this).find('input, select').each(function () { var field = $(this).attr('name'); comment_row[field] = $(this).val(); }); var pp_id = $("input.cksd_praise_pid").val(); //console.log($(this)); var current_form = $(this); var comment_id = $(this).children().find("[name='comment_update_id']").val(); var data = {}; if (pp_id) { praise_row.id = pp_id; comment_row.id = comment_id; data = {praise: praise_row, comment: comment_row} } else { data = {praise: praise_row, comment: comment_row}; } //console.log(data); $.ajax({ type: 'post', url: "<?php echo site_url('/praise/save_intime');?>", data: data, dataType: 'json' }).done(function(res) { if ((res.s == 0)) { console.log($(this)); $('input.cksd_praise_pid').val(res.msg.p_id); current_form.children().find("[name='comment_update_id']").val(res.msg.c_id); } console.log(res); }); }});
