[JavaScript知识库]js拼接html表单提交出现的[403]CSRF verification failed. Request aborted.解决方法

JS中提交表单?<button type='submit' >提交</button>，不想用ajax重写put_challenge()方法

function put_challenge(){
    c = layer.open({
        type: 1,
        area: ['242px', '185px'],
        fixed: true,
        title:"Put a New Challenge",
        content:
            "<div class='drag_upload'>"+
            "<form method='post' enctype='multipart/form-data'>"+
                 "<input type='file' id='file' name='filename'  class='file_cselectfile' />"+
                 "<button type='submit' >提交</button>"+
            "</form>"+
            "</div>"+
        "<script>"+
        "layui.use(['form','upload'],function(){"+
        "var form = layui.form;var upload = layui.upload;"+
        "upload.render({"+
            "elem: '#upload_data_chall'"+
            ",url: 'upload.html' "+
            ",accept:'file'"+
            ",exts: 'txt'"+
            ",done: function(res){"+
                "layer.msg('Success');"+
                "console.log(res);"+
                "close_upload();"+
                "}"+
            ",error: function(){"+
                "layer.msg('Submit Challenge Successfully.');"+
                "close_upload();"+
                "console.log(res)"+
                "}"+
            "});"+
        "});"+

        "</script>"

    });

}
