我有一个AJAX请求（通过GET方法）使用以下代码：
<script>
$(document).ready(function(){
$('.attachmentDetailsButton').click(function(){
var $a = $(this);
$.ajax({
type:'GET',
url: '/shipments/attachmentDetails',
dataType:'json',
data: {
'attachmentID': $a.data('id'),
'_token': $('input[name=_token]').val(),
},
success: function(data) {
$('.errorTitle').addClass('hidden');
$('.errorContent').addClass('hidden');
if ((data.errors)) {
setTimeout(function () {
$('#createOrigin').modal('show');
toastr.error('Check your inputs!', 'Error Alert', {timeOut: 5000});
}, 500);
if (data.errors.title) {
$('.errorTitle').removeClass('hidden');
$('.errorTitle').text(data.errors.title);
}
if (data.errors.content) {
$('.errorContent').removeClass('hidden');
$('.errorContent').text(data.errors.content);
}
} else {
//toastr.success('Changed Bill To '+data.customer_name, 'Success Alert', {timeOut: 5000});
$('#attachmentIDdetails').html(
'<div id="viewer"><object data="http://www.pdf995.com/samples/pdf.pdf" type="application/pdf" width="100%" height="100%"><iframe src="http://www.pdf995.com/samples/pdf.pdf" style="border: none;" width="100%" height="100%">This browser does not support PDFs.

$('.modal-footer').html(
'<button type="button" class="btn btn-default" data-dismiss="modal">Close</button><a href="/files/i/'+data.url_string+'" target="_blank"><button type="button" class="btn btn-success"><span id="" class="glyphicon glyphicon-check"></span> View More Details</button></a>'
);
}
},
error: function (jqXHR, textStatus, errorThrown) {
if (jqXHR.status == 500) {
alert('Internal error: ' + jqXHR.responseText);
} else {
alert('Unexpected error.');
}
}
});
});
});
</script>
正如你在我的脚本中看到的那样，你可以看到返回数据放在名为“attachmentIDdetails”的div中的位置 - 以及它返回的一个特定字段“data.attachmentPath”我需要有一个单词开始删除。每次返回“/public/storage/etc.etc。”，我需要它只删除“/ public”部分。这些数据来自MySQL数据库，并且有一个理由在开头添加“/ public”，因此无法更改，因此我希望我可以在响应中直接删除数据。 / p>

我已将子字符串添加到正确的位置，更改此行
'<div id="viewer"><object data="http://www.pdf995.com/samples/pdf.pdf" type="application/pdf" width="100%" height="100%"><iframe src="http://www.pdf995.com/samples/pdf.pdf" style="border: none;" width="100%" height="100%">This browser does not support PDFs.

我建议使用regex。
此正则表达式删除路径名[/^\/[\w\d]+\//]
var data = "/public/storage/etc.etc.";
data = data.replace(/^\/[\w\d]+\//, '');
console.log(data);

使用String＃replace（）
重置该属性data.attachmentPath = data.attachmentPath.replace('/public','')
