js 实现图片上传

参考链接

点击按钮直接上传文

/*批量导入*/
    /*#load:为按钮,点击后生成一个隐藏的input file标签*/
    $('#load').after('<input type="file" id="load_xls" name="file" style="display:none" onchange ="uploadFile()">');
    $('#load').click(function(){
        document.getElementById("load_xls").click();
    });
    function uploadFile() {
        var myform = new FormData();
        myform.append('file',$('#load_xls')[0].files[0]);
        $.ajax({
            url: "admin.php?r=org/orguser/addusers",
            type: "POST",
            data: myform,
            contentType: false,
            processData: false,
            success: function (data) {
                console.log(data);
            },
            error:function(data){
                console.log(data)
            }
        });
    }
后台接受
if (request()->file('file') != null){
			echo "00000";
		}else{
			echo "111111";
		}


2，打包form表单进行上传文件
