HomeWeb Front-endJS TutorialIE和FireFox(FF)中js和css的不同_javascript技巧

在IE和FireFox(FF)中js和css的不同
css:
1.
ul标签中FF中有个padding值,却没有margin值,而在IE中正好相反
解决办法:将ul的padding和margin都设为0(也可以不是0)如:padding:0;margin:0;list-style:none;
js:
1.
IE中innerText在FF中没有,使用textContent;
eg:

复制代码 代码如下:

var obj=document.getElementById("_td");
var text;
if(obj.innerText) {
text=obj.innerText;
} else if(obj.textContent) {
text=obj.textContent;
}

2.
在Ajax中返回对象状态IE可以使用readystate但是在FF中必须为readyState,所以最好是都写成readyState
3.获取IE和FF中的键盘返回值,

function test(e) {
var keyc=GetKeyCode(e);
alert(keyc);
}
function GetKeyCode(e) {//取得不同浏览器下的键盘事件值
var keyc;
if(window.event) {//ie键盘事件
keyc=e.keyCode;
} else if (e.which) {//火狐
keyc=e.which;
}
return keyc;
}
4.为对象添加移除事件
var obj=document.getElementById("_tname');
添加事件:
if(obj.attachEvent) {
obj.attachEvent("onchange",function() {
otherfunction(params);//这里可以给其实方法传参,也可以直接调用其它方法
});
} else if(obj.addEventListener) {
obj.addEventListener("change",function() {
otherfunction(params);
},false);
}
移除事件:
obj.onclick=null;
/*下面的代码为什么不行,IE下输出obj.onclick竟然为anonymous,希望高手能帮忙解决
if(obj.detachEvent) {
obj.detachEvent("onchange",test);
} else if(obj.removeEventListener) {
obj.removeEventListener("change",test,false);
}*/
5.
IE中event.x和event.y
在FF中只有event.pageX,event.pageY
都有event.clientX和event.clientY属性
解决办法:
var x=e.x?e.x:e.pageX;//e为event对象传进来的参数
6.IE下 input.type属性为只读,但是MF下可以修改
7.在 IE 中,getElementsByName()、(document.all[name] (还未测试成功))均不能用来取得 div元素(是否还有其它不能取的元素还不知道)。
8.通过js来触发事件



9.IE下event对象有srcElement属性,Firefox下,event对象有target属性
var obj=e.srcElement?e.srcElement:e.target;//e为event对象传进来的参数
//从这里下面的还未测试
10.在FF中自己定义的属性必须getAttribute()取得
11.节点问题
IE中使用parentElement parement.children,而FF中使用parentNode parentNode.childNodes
childNodes的下标的含义在IE和FF中不同,FF使用DOM规范,childNodes中会插入空白文本节点。
FF中节点没有removeNode方法,必须使用如下方法 node.parentNode.removeChild(node)

Python vs. JavaScript: A Comparative Analysis for DevelopersPython vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AM

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Python vs. JavaScript: Choosing the Right Tool for the JobPython vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AM

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript: Understanding the Strengths of EachPython and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AM

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

The Relationship Between JavaScript, C  , and BrowsersThe Relationship Between JavaScript, C , and BrowsersMay 01, 2025 am 12:06 AM

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting.
