escape,encodeURI和encodeRUIComponent的区别

JavaScript中有三个URL函数编码,他们都是全局的;

区别在于:

encodeURI只将URI中的空格和非AscII字符进行编码,编码后的URI可以正常访问(ajax中文问题可以使用encodeURI对url进行编码)

encodeURIComponent 除了将所有的非ASCII字符编码外,还将一些特殊字符进行编码,如?#:,&等,编码后的URI不可访问

escape 功能和encodeURIComponent功能一样,但是编码后的URI是可以访问的,对使用没有任何影响

例如:

var url = 'http://www.oschina.net/project/search?q=tomcat'; var results = ['URI: ' + url]; // escaperesults.push('escape: ' + escape(url));// encodeURIresults.push('encodeURI: ' + encodeURI(url));// encodeURIComponentresults.push('encodeURIComponent: ' + encodeURIComponent(url)); document.write(results.join('')); /*URI: http://labs.phpz.org/jstest/null.html?a=TEST1&b=hello world#escape: http%3A//labs.phpz.org/jstest/null.html%3Fa%3DTEST1%26b%3Dhello%20world%23encodeURI: http://labs.phpz.org/jstest/null.html?a=TEST1&b=hello%20world#encodeURIComponent: http%3A%2F%2Flabs.phpz.org%2Fjstest%2Fnull.html%3Fa%3DTEST1%26b%3Dhello%20world%23*/
