I have a problem with my jQuery script that send data via POST method. The problem is whenever it sends data via Ajax that has an "&" ampersand in the sentence, it will cut the sentence when found "&".
我的jQuery脚本有一个问题，它通过POST方法发送数据。问题是，每当它通过Ajax发送带有“&”和号的数据时，当它发现“&”时，它就会把句子删掉。

htmlentites
This function is identical to htmlspecialchars() in all ways, except with htmlentites(), all characters which have HTML character entity equivalents are translated into these entities.
这个函数与htmlspecialchars()完全相同，除了htmlentites()之外，所有具有HTML字符实体的字符都被转换成这些实体。
If you're wanting to decode instead (the reverse) you can use html_entity_decode().
如果您想要解码(相反)，可以使用html_entity_decode()。
Example:
例子:
echo htmlentities("&"); // &
if your directly doing this in the browser you should be able to use:
如果您直接在浏览器中这样做，您应该能够使用:
encodeURIComponent(string input);
Example:
例子:
encodeURIComponent($.trim($("input[name=t-tim_rendered-"+id+"]").val().toString()));

I've been having a huge problem exactly with this situation.
我一直对这种情况有很大的问题。
This is just to say that the last answer from Andrew Koester is the perfect answer I was looking for.
这只是说，Andrew Koester的最后一个答案是我一直在寻找的完美答案。
In case you are passing multiple form entries from a jQuery form to PHP through the .ajax() call like this:
如果您正在通过.ajax()调用从jQuery表单传递多个表单条目到PHP，如下所示:
data: "name=" + name + "&message=" + message + ...
数据:“name = " +名称+“消息= " +信息+……
DON'T USE THIS METHOD, it will block the ampersand(&) character from being written by the user on any of the input fields of your form.
不要使用此方法，它将阻止用户在窗体的任何输入字段上写入&字符。
Use this one instead as suggested by Andrew:
用这个代替安德鲁的建议:
data: {"name": name, "email": email, "subject": subject, "comments": comments},
数据:{"name": name， "email": email， "subject": subject， "comments": comments，
This way the user can write any kind of special character whithout worrying a about conflicting with the ajax declaration.
通过这种方式，用户可以编写任何类型的特殊字符，以避免与ajax声明冲突。

You can use a native javascript escape() function
可以使用本机javascript escape()函数
In line 74
在第74行
data: : "&task_d=" + escape(task_d) + ""
Alternatively, you could enclose your query string values in quotes
或者，您可以将查询字符串值括在引号中
data: : "&task_d='" + task_d + "'"

If you pass your data parameter as a Javascript object, it will convert the characters for you (and IMO make the code look neater). So you should change your $.ajax call to the following:
如果您将数据参数作为Javascript对象传递，它将为您转换字符(在我看来，代码看起来更整洁)。所以你应该改变你的美元。ajax调用如下:
data: {"user_id": user_id, "time_r": time_r, "task_d": task_d, "p_id": p_id, "df": finished},

You could use 'encodeURIComponent' to accomplish the URL encoding for that component. I used this and validated with browsers IE, Firefox, and Chrome.
您可以使用“encodeURIComponent”来完成该组件的URL编码。我使用了这个，并通过浏览器IE、Firefox和Chrome进行了验证。
