Solution to IE jQuery AJAX garbled problem

When using jQuery for data requests, you will inevitably encounter some garbled code problems that appear in IE browsers. For example, characters are escaped, Chinese characters are displayed as garbled characters, etc. This article will introduce some common IE jQuery AJAX garbled problems and provide solutions.

1. Character escaping problem

In IE browser, if the returned data contains special characters, jQuery will automatically escape the characters. At this time, the returned data needs to be restored. We can use JavaScript's unescape function to decode the returned string.

For example, if we return the following data on the server side:

{
    "username": "张三",
    "email": "zhangsan@example.com"
}

Use jQuery to make a request on the client side:

$.ajax({
    url: "www.example.com/getData",
    type: "GET",
    dataType: "json",
    success: function(data) {
        var username = unescape(data.username);
        var email = unescape(data.email);
    }
});

This can solve the problem of special characters in the returned data question.

2. Chinese garbled code problem

In IE browser, Chinese data often has garbled code problem. This is because under the IE browser, the encoding method of Chinese data is GB2312, while the encoding method transmitted on the server side is generally UTF-8. If there is no encoding conversion during the transmission process, the problem of Chinese garbled characters will occur.

The solution is to encode the data into GB2312 format on the server side. When using jQuery on the client side, just set it to text in the dataType attribute:

$.ajax({
    url: "www.example.com/getData",
    type: "GET",
    dataType: "text",
    success: function(data) {
        var data = unescape(data);
        // 将数据转换为JSON格式
        data = JSON.parse(data);
        var username = data.username;
        var email = data.email;
    }
});

3. The return header lacks Content- Type attribute

In IE browser, if the data returned by the server does not set the Content-Type attribute, garbled characters will also occur. The solution is to add the Content-Type attribute to the HTTP header on the server side and set it to text/plain or text/html.

For example, the method of setting Content-Type in PHP is as follows:

header("Content-Type: text/plain; charset=gbk");

The method of setting Content-Type in Java is as follows:

response.setContentType("text/plain;charset=gbk");

Set Content in .NET -Type method is as follows:

Response.ContentType = "text/plain;charset=gbk";

Summary: Solution to the IE jQuery AJAX garbled problem

When using jQuery for data requests, you often encounter the garbled problem under the IE browser. This type of problem can be solved through the following steps:

1. Decode the special characters of the returned data.
2. When using jQuery on the client side, set the dataType attribute to text.
3. When the server returns data, set the Content-Type attribute to text/plain or text/html.

Through the above solutions, we can easily solve the IE jQuery AJAX garbled problem and ensure that the website runs normally under the IE browser.
