ie browser injects javascript except bho

In IE browser, we can inject JavaScript code in many ways. In addition to BHO (browser auxiliary object), there are other ways to achieve this function. This article will introduce several of these methods and discuss their advantages and disadvantages.

1. IE extension

IE extension is a very popular way to inject JavaScript code. By creating an IE extension and adding the address of the target webpage to its configuration file, you can automatically inject the specified JavaScript code when the target webpage loads.

Advantages:

1. IE extension can achieve comprehensive control of the IE browser, including web page access, DOM operations, etc.
2. By adding multiple target web addresses in the configuration file, the same JavaScript code can be automatically injected into multiple web pages.
3. You can easily manage all extensions through the IE extension management interface.

Disadvantages:

1. IE extension development requires the use of a special SDK, and the development cost is high.
2. IE extension can only be used in IE browser and cannot be used across browsers.
3. IE extensions will increase system resource usage and may cause the browser to slow down.

2. Proxy server

Proxy server is another common way to inject JavaScript code. By intercepting the request for the target web page on the proxy server, you can inject the specified JavaScript code on the server side and return the modified response to the client browser.

Advantages:

1. The proxy server has the characteristics of cross-browser and cross-platform, and can realize injection into multiple browsers.
2. By intercepting browser requests, the requests can be processed on the server side, which enhances code control.
3. Can manage multiple websites in a unified manner to improve management efficiency.

Disadvantages:

1. The development and maintenance costs of proxy servers are relatively high.
2. Proxy servers will affect the access speed of the website, especially during times of high traffic.
3. The proxy server needs to be installed in the network. If the network is unstable or has low security, there may be security risks.

3. Injection tool

The injection tool is a more convenient way to inject JavaScript code. By adding the address of the target webpage and the JavaScript code to be injected in the injection tool, the specified JavaScript code can be automatically injected when the target webpage is loaded.

Advantages:

1. The injection tool is simple to use, requires no development costs, and is suitable for temporary code injection needs.
2. The injection tool has the characteristics of cross-browser and cross-platform, and can be used for multiple browsers.
3. The injection tool can achieve unified management of multiple websites and improve management efficiency.

Disadvantages:

1. The injection tool does not have as high control as the IE extension and proxy server. The injected code may be recognized as malicious code by the browser or anti-virus software. Resulting in manslaughter.
2. The injection tool can only be used for a single browser and cannot achieve batch injection of multiple browsers.

To sum up, in addition to BHO, there are other ways to inject JavaScript code into IE browser, such as IE extensions, proxy servers and injection tools. When choosing an injection method, you need to make a choice based on specific needs and conditions, taking into account factors such as development cost, control strength, compatibility, stability, and security.
