JS：追加变量URL不重复 [英] JS: Append variable to URL without repeating

问题描述

可能重复：结果
  更改URL参数与jQuery？

目前，我有一个＆LT; D​​IV＆GT; 标签，看起来像一个按钮，并与重定向到同一个页面一个onClick函数改变URL只是增加了＆安培; view_all =是或＆放大器; view_all =否来的网址

Currently, I have a <div> tag that looks like a button and changes the URL with an onClick function which redirect to the same page just adds &view_all=Yes or &view_all=No to the URL.

＆LT; D​​IV的onclick =JavaScript的：window.location.href ='？page.php行动=列表的志愿者应用和放大器;查看，所有=否';＆GT;隐藏关闭的应用程序＆LT; / DIV＆GT;

好吧，我增加了新功能的网站，我需要能够追加了＆安培; view_all =是或＆安培; view_all =否来的URL重定向，而不​​是他们到底是因为我有，我不能失去URL其他变量。

Well, I am adding a new feature to the website and I need to be able to append that &view_all=Yes or &view_all=No to the end of the URL instead of redirecting them because I'll have other variables in the URL that I can't lose.

我已经找到了一种方法做追加但它一直添加＆放大器; view_all 变量URL的末尾，以便它看起来像这样<$c$c>page.php?action=list-volunteer-apps&view-all=No&view_all=Yes&view_all=No.

I have figured out a way to do the append but it keeps adding the &view_all variables to the end of URL so it looks like this page.php?action=list-volunteer-apps&view-all=No&view_all=Yes&view_all=No.

这是我做的追加方式：
<$c$c>onclick=\"javascript:window.location.assign(window.location.href+='&view-all=No');\"

推荐答案

您可以使用普通的前pression在替换字符串值：

You can use regular expression to replace the value in a string:

$(this).attr("onclick", function(i, val) {
    return val.replace(/view-all=(Yes|No)/, function() {
        return "view-all=" + ((arguments[1] || "") == "Yes" ? "No" : "Yes");
    });
});
