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);

};
