Call Javascript function from URL/address bar
提问by DazManCat
Is it possible to call a javascript function from the URL? I am basically trying to leverage JS methods in a page I don't have access to the source.
是否可以从 URL 调用 javascript 函数？我基本上是在尝试在我无法访问源代码的页面中利用 JS 方法。
Something like: http://www.example.com/mypage.aspx?javascript:printHelloWorld()
就像是： http://www.example.com/mypage.aspx?javascript:printHelloWorld()
I know if you put javascript:alert("Hello World");into the address bar it will work.
我知道如果你javascript:alert("Hello World");输入地址栏它会工作。
I suspect the answer to this is no but, just wondered if there was a way to do it.
我怀疑这个答案是否定的，只是想知道是否有办法做到这一点。

There isn't from a hyperlink, no. Not unless the page has script inside specifically for this and it's checking for some parameter....but for your question, no, there's no built-in support in browsers for this.
没有来自超链接，不。除非页面内部有专门用于此的脚本并且它正在检查某些参数......但对于您的问题，不，浏览器中没有内置支持。
There are however bookmarkletsyou can bookmark to quickly run JavaScript functions from your address bar; not sure if that meets your needs, but it's as close as it gets.
然而有书签工具，你可以书签快速从地址栏运行JavaScript的功能; 不确定这是否满足您的需求，但它尽可能接近。

Write in address bar
在地址栏中写入
javascript:alert("hi");
Make sure you write in the beginning: javascript:
确保你在开头写： javascript:

You can use Data URIs.
For example:
data:text/html,<script>alert('hi');</script>
您可以使用数据 URI。例如：
data:text/html,<script>alert('hi');</script>

to your html-code, and when you click on 'Click me' hyperlink, javascript will appear in url-bar and Alert dialog will show
到您的 html 代码，当您单击“单击我”超链接时，javascript 将出现在 url-bar 中，并且警报对话框将显示

About the window.location.hashproperty:
Return the anchor part of a URL.
关于window.location.hash属性：
返回 URL 的锚点部分。
Example 1:示例 1：
//Assume that the current URL is
var URL = "http://www.example.com/test.htm#part2";
var x = window.location.hash;
//The result of x will be:
x = "#part2"
Exmaple 2:
示例 2：
$(function(){
setTimeout(function(){
var id = document.location.hash;
$(id).click().blur();
}, 200);
})
Example 3:
示例 3：
var hash = "#search" || window.location.hash;
window.location.hash = hash;
switch(hash){
case "#search":
selectPanel("pnlSearch");
break;
case "#advsearch":
case "#admin":
}

Using Eddy's answer worked very well as I had kind of the same problem. Just call your url with the parameters : "www.mypage.html#myAnchor"
使用 Eddy 的答案效果很好，因为我遇到了同样的问题。只需使用参数调用您的网址：“www.mypage.html#myAnchor”
Then, in mypage.html :
然后，在 mypage.html 中：
$(document).ready(function(){
var hash = window.location.hash;
if(hash.length > 0){
// your action with the hash
}
});

you can use like this situation:
for example, you have a page: http://www.example.com/page.phpthen in that page.php, insert this code:
您可以使用这种情况：例如，您有一个页面： http://www.example.com/page.php然后在该 page.php 中插入以下代码：
if (!empty($_GET['doaction']) && $_GET['doaction'] == blabla ){
echo '<script>alert("hello");</script>';
}
then, whenever you visit this url: http://www.example.com/page.php?doaction=blabla
然后，每当您访问此网址时： http://www.example.com/page.php?doaction=blabla
then the alert will be automatically called.
然后将自动调用警报。
