javascript 分享一个获取url get参数的方法
本函数使用到了javascript中的indexOf方法和split方法。具体代码如下:
<code class="language-javascript">function getPara(para) { if (location.href.indexOf("?") == -1) { // 没有参数,则Do nothing. return null; } else { // 取得GET请求?号后面的字符串 var urlQuery = location.href.split("?"); if (urlQuery[1].indexOf("&") == -1) { //只有一个参数 if (urlQuery[1].indexOf("=") == -1) { //没有等号,没有参数,则Do nothing return null; } else { var keyValue = urlQuery[1].split("="); var key = keyValue[0]; var value = keyValue[1]; if (key == para) { return value; } } } else { // 解析参数 var urlTerms = urlQuery[1].split("&"); for (var i = 0; i </code>
直接调用getPara函数即可获取某个url的参数。
本文章的js/html/php/css代码均可以复制到这个页面进行在线调试,你不妨试一下。
