step
1. The front end sets the url
2. The back end queries the meta field data of the table according to the passed parameters, and passes it to the front end
3. The front end receives the data, and the traversal loop puts it into the column
Code
Front-end code:
var cols = [];
function dydatagrid() {
if(!interId){
dLong.layerInfo("请选择接口！");
return;
}
var postdata={
interId: interId
}
dLong.getJSON("/BaexportController/toList",postdata,function(data){
if (data.success) {
cols = [];// 初始化
$.each(data.fielddata,function(index,row){
cols.push({
field: row.code, title: row.name,sort:'true',align:'center',width: 140}); // 元数据标题栏设置
});
// var obj2 = deepClone(data.griddata);
hstable(data.griddata,true) //数据
}else {
hstable([])
}
},true);
}
// 导出接口数据导出存储表格
function hstable(data) {
var table = layui.table;
var ins1=table.render({
