[英]Javascript: how can I append variables to the url?
how can I append variables to an URL with javascript without navigating to the url ? 如何在不导航到URL的情况下使用javascript将变量附加到URL?
thanks 谢谢
To append variables to the hash (as Matthew suggested ), you can do the following in plain JavaScript: 要将变量附加到散列(如Matthew建议的那样 ),您可以在纯JavaScript中执行以下操作:
window.location.hash = 'varA=some_value;varB=some_value';
This will add #varA=some_value;varB=some_value
to your URL. 这会将
#varA=some_value;varB=some_value
到您的URL。 It will not refresh the page unless the hash value is equal to an anchor name or an element id within the document. 除非哈希值等于文档中的锚名称或元素id,否则它不会刷新页面。
Then to check if a hash value is present, simply do the following: 然后检查是否存在哈希值,只需执行以下操作:
var i, variables = window.location.hash.split(';');
if (variables.length > 0) {
// Variables present in hash
for (i = 0; i < variables.length; i++) {
keyValuePair = variables.split('=');
// keyValuePair[0] would be the key (variable name)
// keyValuePair[1] would be the value
}
}
else {
// No variables in the hash
}
You may also want to check out the following Stack Overflow post on issues related to the URL encoding of the hash part in different browsers: 您可能还想查看以下Stack Overflow帖子,了解与不同浏览器中哈希部分的URL编码相关的问题:
You can modify window.location.hash
. 您可以修改
window.location.hash
。 Anything else will cause a navigation. 其他任何东西都会导致导航。
I am not sure about that, but how is it with this?: 我不确定,但这是怎么回事?:
document.url + myVar + 'myString';
Though Javascript is not my language :P 虽然Javascript不是我的语言:P
