easyui之datagrid为啥后台返回的数据在前台不显示

Posted 2023-03-15

参考技术A 用的是php+easyUI做的开发，EasyUI datagrid绑定数据源有问题，就是数据显示不出来。
<table id="family_info" class="easyui-datagrid" title="家庭成员信息" style="width:100%;height:auto" data-options="
iconCls: 'icon-edit',
fitColumns:true,
rownumbers:true,
url:'__URL__/stuFamilyJson',
method:'get',
singleSelect: true,
toolbar: '#toolbar'">
原来在win下做开发，这样写是好使的，顺道贴出stuFamilyJson方法的代码：
public function stuFamilyJson()
$tb=D('StuFamily');
$familyInfo=$tb->where('stu_id='.session('userId'))->select();
foreach ($fam www.hnnedu.com ilyInfo as $key=>$familyInfoEach)
$familyInfo[$key]=$tb->parseFieldsMap($familyInfoEach);
echo $familyInfo=json_encode($familyInfo);

用浏览器开发者工具查看，得到返回值如下：
["id":"1","stuId":"1","folkName":"\u7236\u4eb2\u5927\u4eba","folkRelation":"\u7236\u5b50","folkCompany":"\u7236\u4eb2\u7684\u5355\u4f4d","folkPosition":"\u5de5\u4eba2","folkTel":"12345678910","folkAddress":"\u7ed9\u5927\u5bb6\u8bf4\u670di\u4e3au\u5346","id":"2","stuId":"1","folkName":"\u6bcd\u4eb2\u5927\u4eba","folkRelation":"\u6bcd\u5b50","folkCompany":"\u6bcd\u4eb2\u7684\u5355\u4f4d","folkPosition":"\u5de5\u4eba","folkTel":"12345678910","folkAddress":"\u5bf9\u65b9\u7b54\u590d","id":"6","stuId":"1","folkName":"\u5144\u957f\u5927\u4eba","folkRelation":"\u5144\u5f1f","folkCompany":"\u65e0","folkPosition":"\u65e0","folkTel":"123456","folkAddress":"\u70ed\u70ed\u70ed\u4ed6 \u5c14\u7279\u8ba9\u4ed6"]
注：此部分汉字都编码了，这里就不还原。
但是现在这样写，前台就显示不出数据了！
把返回的数据直接粘贴到一个json文件，url改为该json文件，就能正常显示了。
但是，这终究不是个好办法，毕竟要和数据库交互，当然你可能说让后台操作，将结果写入json文件，这样确实可以，不过我不是很喜欢。
又想到了这样写：
<script type="text/javascript">
$(document).ready(
$.post("__URL__/stuFamilyJson",
function(data)
data=eval("("+data+")");
$("#family_info").datagrid('data':data);

)
);
</script>
