无法获取tr元素的属性值 [英] Cannot getting attribute value of the tr element

问题描述

我想将数据从表保存到数据库，所以使用jquery和html属性来获取表值，我区分表上的新旧数据，在tr（表行）上添加属性，即data_histry =new 或者data_histry =old



当我保存时，jquery无法从表属性中获取此属性..





请帮助



我的尝试：



在表格中添加数据

I want to save data from table to database so using jquery, and html attributes to get the table values and i am differentiating new and old data on table from adding a attribute on tr(table row) that is data_histry="new" or data_histry="old"

when i saving then jquery cannot get this attribute from table attribute..


please help

What I have tried:

adding data in table

var markup = "<tr id='tab" + tabid + "' class='test old' style='background-color:#E9E9E9;' data_type='test' data_histry='old'><td class='data-name' medi-id='"+ data[i].tid +"'>" + data[i].name + "</td><td class='data-dis'>" + data[i].descript + "</td><td><button test-id='" + data[i].id + "' type='button' class='btn btn-danger table-delete'></button></td></tr>";

$("#table-body").append(markup); 

并希望通过循环从属性获取属性

and want to get property from attribute by the process from loop

console.log($('#tab'+i).attr('data_histry'));

其中#tab是id tr和我正在计算变量



和在控制台上它给我



undefined

where #tab is id of tr and i is counting variable

and on console its giving me

undefined

推荐答案

（＃table-body）。append（markup）;

("#table-body").append(markup);

并希望通过循环从属性获取属性

and want to get property from attribute by the process from loop

console.log(

（'＃tab'+ i）.attr（'data_histry'））;

('#tab'+i).attr('data_histry'));

其中#tab是tr的id而我正在计算变量



并且在控制台上它给我



undefined

where #tab is id of tr and i is counting variable

and on console its giving me

undefined
