fastadmin自定义导出数据

html代码

<a class="btn btn-info btn-myexcel-export" title="导出" href="javascript:;"><i class="fa fa-download"></i> 导出</a>

js代码

在相应页面的js代码中补充按钮脚本

// 初始化表格
table.bootstrapTable({
      
	//...
})
// 自定义导出按钮
$(document).on("click", ".btn-myexcel-export", function () {
     
	var page = table.bootstrapTable('getData'); // 获取页面数据
	let ids = [];
	let id_data = '';
	// 取出当前页面的id
	$.each(page,function(i,v){
     
	    ids.push(v.id)
	    if(i == 0){
     
	        id_data = v.id;
	    }else{
     
	        id_data += ','+v.id;
	    }
	})
	layer.confirm("请选择导出的选项", {
     
	    title: '导出数据',
	    btn: ['全部数据','当前页数据(' + ids.length + '条)'],
	    yes: function (index, layero) {
     
	        // 全部数据
	        Layer.close(index);
	        top.location.href="/xxx/xx/export?id_data="
	    },
	    btn2: function (index, layero) {
     
	        // 当前页面数据
	        top.location.href="/xxx/xx/export?id_data="+id_data
	    }
	})
	});
// 为表格绑定事件
Table.api.bindevent(table);

php代码

phpexcel的使用可参考我之前写的教程 Laravel和TP导出数据Excel

/**
