提问by Jerielle
I got a problem I am submitting a simple form that has a small data and when I checked in the consoletab the URL of ajax seems to be working but after the ajax was processed it will alert an error and it is redirected to my homepage and from the console tab I have this weird error:

未捕获的异常：内存不足
In my ajax I have this simple code only:
在我的 ajax 中，我只有这个简单的代码：
$("#add-comment").on('click', function() {
var id = $('input[name=\'review_id\']').val();
var customer_id = $('input[name=\'customer_id\']').val();
var $comment = $('textarea[name=\'user_comment\']').val();
var sample = "test";
$.ajax({
url: 'index.php?route=product/product/writeSubComment',
type: 'post',
dataType: 'json',
data: { text: sample },
beforeSend: function() {
},
success: function(data) {
console.log(data.test);
},

在我的 PHP 控制器中，我有这个功能
public function writeSubComment() {
$json = array();
$json['test'] = $this->request->post['text'];
$this->response->addHeader('Content-Type: application/json');
$this->response->setOutput(json_encode($json));
}

From your description of being redirected to your homepage, but having no code in your ajax response sections to do this, I suspect that the element #add-comment is a submit button in your form.
根据您对被重定向到主页的描述，但在 ajax 响应部分中没有执行此操作的代码，我怀疑元素 #add-comment 是表单中的提交按钮。
If this is the case, then your form may be submitting at the same time the ajax code is running when you click the #add-comment submit button. This would explain the out of memory error as the ajax javascript is being expunged while the page redirects.
如果是这种情况，那么当您单击 #add-comment 提交按钮时，您的表单可能会在 ajax 代码运行的同时提交。这将解释内存不足错误，因为在页面重定向时 ajax javascript 正在被清除。
You would need to prevent your form from submitting, and let the success() or failure sections handle the next step (i.e. refreshing the page, updating the comments box). One way to do this would be to change
您需要阻止表单提交，并让 success() 或 failure 部分处理下一步（即刷新页面、更新评论框）。一种方法是改变
$("#add-comment").on('click', function() {
...
to
到
$('#add-comment').on('click', function(event){
event.preventDefault();
...
or change the submit button from
或更改提交按钮
<button type="submit" ...>Add comment</button>
to
到
<button type="button" ...>Add comment</button>
or change the form tag like this
或像这样更改表单标签
<form onsubmit="return false;">
This is my best guess from the information I have available.
这是我从现有信息中最好的猜测。

I was having a similar problem while testing in Firefox. Changing the button's typefrom submitto buttonworked for me.
我在 Firefox 中测试时遇到了类似的问题。更改按钮是type从submit到button为我工作。
<button type="submit" ...>Add comment</button>
to
到
<button type="button" ...>Add comment</button>
