1.通过a标签的方式来下载
<a href='' target='_blank'></a>
2.通过提交form表单的方式
var $form = $('<form action="'+url+'" method="post" target="rfFrame"></form>');
angular.forEach(d,function(v,k){
v = JSON.stringify(v);
var $input = $('<input type="hidden" name="'+k+'"/>');
$input.attr('value',v);
$form.append($input);
});
$element.append($form);
$form.submit();
$form.remove();3.通过http的请求拿到文件流的方式
$http({
url : $scope.url,
method : 'post',
data : $scope.form.formdata,
responseType : 'arraybuffer',
}).then(function(d){
var data = d.data;
var blob = new Blob([data], {type: "text/plain"});
//var blob = new Blob([data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"});//xlsx
//var blob = new Blob([data], {type: "application/vnd.ms-excel"});//xls
var downloadTitle = '';
if(d.headers('content-disposition').indexOf('filename') != -1){
downloadTitle = d.headers('content-disposition').split(';')[1].split('=')[1];
downloadTitle = decodeURI(downloadTitle);
}
if(typeof window.navigator.msSaveBlob !== 'undefined'){
window.navigator.msSaveBlob(blob, downloadTitle);
}else{
var objectUrl = URL.createObjectURL(blob);
var aForExcel = $("<a download='"+downloadTitle+"'><span class='forExcel'></span></a>").attr("href",objectUrl);
$("body").append(aForExcel);
$(".forExcel").click();
aForExcel.remove();
}
});
