What should I do if javascript paging is not compatible with IE?

With the development of the Internet, websites have become more and more interactive, and the paging function has become one of the necessary functions for most websites. As a front-end scripting language, JavaScript also plays an important role in paging implementation. However, when using JavaScript to implement the paging function, we will find compatibility issues between IE and other browsers, which brings a lot of trouble to developers. This article will discuss the issue of JavaScript paging IE incompatibility.

1. Issues unique to IE browser

In the process of implementing JavaScript paging, we often use DOM operations to implement functions such as data rendering and page jumps. However, since IE browser implements DOM The method is different from other browsers, so you need to pay attention to some issues when using DOM operations.

1. document.createElement creates a node

When using document.createElement('a') to create a tag in IE, you need to add the href attribute to it, otherwise the page cannot Jump correctly.

var link = document.createElement('a');
link.href = href; // IE需要增加一个href属性
link.innerHTML = page;
pageDiv.appendChild(link);

2. parentNode property

In other browsers, if an element has no parent node, calling its parentNode property will return null. However, in IE browser, if an element has no parent node, calling its parentNode attribute will report an error.

Therefore, we need to first determine whether the current element has a parent node when using the parentNode attribute.

if (element.parentNode) {
  element.parentNode.removeChild(element);
}

3. innerHTML attribute

In IE browser, when the innerHTML attribute contains a script tag, the content of the script tag will be automatically executed. This will lead to some unexpected situations, such as page jump failure, etc.

Therefore, we need to pay attention when using the innerHTML attribute, especially during the paging implementation process, to avoid inserting script tags in innerHTML.

2. Compatibility solutions

Facing the special situation of IE browser, we can adopt some compatibility solutions. Here are some common methods.

1. Use libraries such as jQuery to encapsulate DOM operations.

This method is relatively simple. We can directly use its encapsulated DOM operation method by introducing class libraries such as jQuery without worrying about the compatibility of IE browsers. However, this will increase the loading time of the web page and the corresponding cost, and is not suitable for lightweight websites.

2. Use the document.createEvent method

document.createEvent is a method of creating and initializing events, which can be used to be compatible with the event mechanism of the IE browser.

var event = document.createEvent("HTMLEvents");
event.initEvent("click", true, true); // 初始化事件
element.dispatchEvent(event); // 触发事件

3. Use IE’s unique document.createEventObject method

IE browser provides the document.createEventObject method, which can be used to create event objects.

var event = document.createEventObject();
element.fireEvent('onclick', event); // 触发事件

4. Summary

When using JavaScript to implement paging, the compatibility issues between IE and other browsers will indeed cause some trouble to developers. Therefore, we need to have a deep understanding of the DOM operation method of IE browser and adopt corresponding processing methods to avoid these compatibility issues.

The above is the solution for JavaScript paging that is not compatible with IE. I hope it can provide some useful help to developers who use JavaScript to implement paging.
