JavaScript的方法和技巧
这篇介绍javascript方面的日志,我在是Clang上看到的。作者介绍挺全面的,所以转载过来让感兴趣的朋友看一下。呵呵~~~
有些时候你精通一门语言,但是会发现你其实整天在和其它语言打交道,也许你以为这些微不足道,不至于影响你的开发进度,但恰恰是这些你不重视的东西会浪费你很多时间,我一直以为我早在几年前就已经精通JavaScript了,直到目前,我才越来越觉得JavaScript远比我想象的复杂和强大,我开始崇拜它,
趁着节日的空隙,把有关JavaScript的方法和技巧整理下,让每个在为JavaScript而烦恼的人明白,JavaScript就这么回事!并希望JavaScript还可以成为你的朋友,让你豁然开朗,在项目中更好的应用~

JavaScript就这么回事1:基础知识
1 创建脚本块
1: <script language=”JavaScript”>
2: JavaScript code goes here
3: </script>
2 隐藏脚本代码
1: <script language=”JavaScript”>
2: <!--
3: document.write(“Hello”);
4: // -->
5: </script>
在不支持JavaScript的浏览器中将不执行相关代码
3 浏览器不支持的时候显示
1: <noscript>
2: Hello to the non-JavaScript browser.
3: </noscript>
4 链接外部脚本文件
1: <script language=”JavaScript” src= "/”filename.js "”> </script>
5 注释脚本
1: // This is a comment
2: document.write(“Hello”); // This is a comment
3: /*
4: All of this
5: is a comment
6: */
6 输出到浏览器
1: document.write(“ <strong> Hello </strong> ”);
7 定义变量
1: var myVariable = “some value”;
8 字符串相加
1: var myString = “String1” + “String2”;
9 字符串搜索
1: <script language=”JavaScript”>
2: <!--
3: var myVariable = “Hello there”;
4: var therePlace = myVariable.search(“there”);
5: document.write(therePlace);
6: // -->
7: </script>
10 字符串替换
1: thisVar.replace(“Monday”,”Friday”);
11 格式化字串
1: <script language=”JavaScript”>
2: <!--
3: var myVariable = “Hello there”;
4: document.write(myVariable.big() + “ <br> ”);
5: document.write(myVariable.blink() + “ <br> ”);
6: document.write(myVariable.bold() + “ <br> ”);
7: document.write(myVariable.fixed() + “ <br> ”);
8: document.write(myVariable.fontcolor(“red”) + “ <br> ”);
9: document.write(myVariable.fontsize(“18pt”) + “ <br> ”);
10: document.write(myVariable.italics() + “ <br> ”);
11: document.write(myVariable.small() + “ <br> ”);
12: document.write(myVariable.strike() + “ <br> ”);
13: document.write(myVariable.sub() + “ <br> ”);
14: document.write(myVariable.sup() + “ <br> ”);
15: document.write(myVariable.toLowerCase() +
