今天在做文件上传遇到一个问题,在ajax回调成功后触发input[type=’file’]元素的事件时始终不能弹出文件选择对话框 ，于是开始各种问题的排除，最终我发现在ajax 异步提交不行，要同步提交才可以 ，ajax配async: false就以了。
$.ajax({
url:
"",
type:
"get",
async:
false,
success:
function (data) {
if (data.isSuccess) {
WindowConfirmDialog(DeleteAndActiveAllData,
"There is data that does not take effect if the draft data will continue to be deleted,whether to continue?",
"Confirm",
"Continue",
"Cancel");
}
else {
e.preventDefault();
$(
"#importSupplierExcel").trigger(
'click');
}
}
});
