我对 AngularJS 相当陌生，我正在尝试使用 ng-csv 从数组生成 .csv 文件。 现在我已经尝试了所有方法，但没有生成文件，我什至尝试了我在互联网上看到的最简单的示例。 我在错误控制台中没有看到任何错误，但仍然没有生成文件。 我在 Windows 下使用 XAMPP 工作。
<!DOCTYPE html>
<html ng-app="APP">
<head>
<meta charset="UTF-8">
<title>angular-count-to example</title>
<style type="text/css">
.element{cursor:pointer;float:left;background-color:#ccc;padding:4px;}
</style>
</head>
<body ng-controller="ExampleController">
<p>{{data}}</p>
<button type="button" ng-csv="data" filename="test.csv">Export</button>
<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>
<script type="text/javascript" src="bower_components/angular-sanitize/angular-sanitize.min.js"></script>
<script type="text/javascript" src="bower_components/ng-csv/src/ng-csv/ng-csv.js"></script>
<script>
angular.module('APP',["ngSanitize","ngCsv"]).
controller('ExampleController', function ($scope) {
$scope.filename = "test";
$scope.data = [{a: 1, b:2}, {a:3, b:4}];
});
</script>
</body>
</html>
上面是我尝试过的最简单的示例，但是即使这样也不起作用。
最佳答案
尝试纯 HTML5 解决方案。这是我不久前做的一个代码块。尝试通过排除无用的参数来进行自定义
function (JSONData, ReportTitle, ShowLabel, reportType, reportName) {
//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
angular.forEach(arrData, function (data, index) {
if (data.date != undefined)
data.date = dateFormat(data.date)
});
var CSV = '';
//Set Report title in first row or line
CSV += ReportTitle + '\r\n\n';
//This condition will generate the Label/Header
if (ShowLabel) {
var row = "";
//This loop will extract the label from 1st index of on array
for (var index in arrData[0]) {
row += index + ';';
}
row = row.slice(0, -1);
//append Label row with line break
CSV += row + '\r\n';
}
//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
var row = "";
//2nd loop will extract each column and convert it in string comma-seprated
for (var index in arrData[i]) {
//var temp = arrData[i][index].toString().replace('.', ',');
//arrData[i][index] = temp;
row += '"' + arrData[i][index] + '";';
}
row = row.split('.').join(",");
row.slice(0, row.length - 1);
//add a line break after each row
CSV += row + '\r\n';
}
if (CSV == '') {
alert("Invalid data");
return;
}
//Generate a file name
var fileName = "MyReport_";
//this will remove the blank-spaces from the title and replace it with an underscore
fileName += ReportTitle.replace(/ /g, "_");
//Initialize file format you want csv or xls
var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);
// Now the little tricky part.
// you can use either>> window.open(uri);
// but this will not work in some browsers
// or you will not get the correct file extension
//this trick will generate a temp <a /> tag
var link = document.createElement("a");
link.href = uri;
//set the visibility hidden so it will not effect on your web-layout
link.style = "visibility:hidden";
link.download = fileName + ".csv";
//this part will append the anchor tag and remove it after automatic click
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
};
