我正在尝试导入CSV并将结果存储在数组中。我正在关注这个jsfiddle
print('AlaSQL v'+alasql.version)
print('Please upload txt, json, csv, tsv, tab, xlsx, xls or html file to see the content')
loadFile = function(event) {
alasql('SELECT * FROM FILE(?,{headers:true})',[event],function(data){
print(data)
});
}
function print(x){
document.getElementById('output').textContent += JSON.stringify(x, null, '\t')+"\n";
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.8.0/xlsx.full.min.js"></script>
<script src="https://rawgit.com/agershun/alasql/develop/dist/alasql.js"></script>
<input id="readfile" type="file" onchange="loadFile(event)"/>
<xmp id="output"></xmp>
当我尝试在Angle 2中使用相同的代码时,出现以下错误
错误:FILE()函数使用错误
我已经安装了alasql npm软件包,下面是我的home.html
和home.ts
代码:
home.html
<input id="readfile" type="file" (change)="loadFile(event)"/>
home.ts
loadFile = function(event) {
alasql('SELECT * FROM FILE(?,{headers:true})',[event],function(data){
console.log(data,"data");
});
}
选择并上传文件时,出现此错误,请参见下面的屏幕截图:
