我用的是从本地选择csv文件上传,文件选择框id为file

if (!$('#file')[0].files.length) {
		alert("请选择数据文件");
	} else {
		var config = {
			delimiter: "",	// auto-detect
			newline: "",	// auto-detect
			header: true,
			dynamicTyping: false,
			preview: 0,
			encoding: "UTF-8",
			worker: false,
			comments: false,
			step: undefined,
			complete: completeFn,//上传成功时执行哪个函数
			error: undefined,
			download: false,
			skipEmptyLines: true,
			chunk: undefined,
			fastMode: undefined,
			beforeFirstChunk: undefined
		}
		
		$('#file').parse({
			config: config
		});
	}

function completeFn(results) {
	//这里我提取了fields,可以根据实际情况提取其他内容
	initDialog(results.meta.fields);

};
