Utilize Angular's $location to add or update the current URL parameter

I'm working on a function for handling multiple parameters in the URL when clicking an element. Specifically, I need to check if parameter pthree exists, update it to a new value without duplicating, and if it doesn't exist, append it to the current URL before reloading the page.

However, I've hit a roadblock trying to update the URL effectively.

This is my current URL structure:

mypage?pone=99.9999999&ptwo=-44.4444444&pthree=1&pfour=1&pfive=1

Snippet of my controller:

$scope.test = function (){
   $location.search('pthree', 0);
}

The issue with this code is that while it does update the URL, it appends #?pthree=0 to the end of the current URL instead of updating the existing parameter directly.

What I actually want is:

mypage?pone=99.9999999&ptwo=-44.4444444&pthree=0&pfour=1&pfive=1

If anyone has any suggestions on achieving this desired result, I would greatly appreciate it. Thank you!

Answer №1

After experimenting with my app, I discovered a solution that worked effectively for me. It involved configuring the HTML5 mode to enhance its functionality. To learn more about HTML5 mode, check out this resource: https://docs.angularjs.org/guide/$location.

However, I encountered another issue when using $location.search({ pThree: '0' }). This action caused all my other parameters to be overwritten, resulting in an undesired URL structure change to ?pThree=0. The workaround was to carefully manage parameter updates by reading them all, modifying pThree, and then rewriting all of them back into place.

Hopefully, this detailed explanation will prove beneficial to others facing similar challenges.

Answer №2

One easy way to achieve this is by following these steps:

// Start with an existing URL that includes parameters
// For example: http://mywebsite.com/page/view?id=123&name=John

// Add a new parameter to the current URL
$location.search().newParam = 'example';

// Update the URL with the new parameter
$location.search( $location.search() );

After performing these actions, your URL will be modified as shown below:

// The updated URL: http://mywebsite.com/page/view?id=123&name=John&newParam=example
