How to delete a cookie?
(13 answers)
Closed 6 years ago.
How would like to with javascript find a cookie that starts with 'AzureAppProxyAccess' and delete that cookie? It always has a series of random numbers at the end of the name. It is in the same domain so I have access to it.
This is what I have tried with jquery but I would like just javascript.
for (cookie in $.cookie()) {
if(cookie.substring(0, 19) === "AzureAppProxyAccess") {
$.removeCookie(cookie);
}
};
You can use indexOf in strings.
cookie.indexOf('AzureAppProxyAccess') > 1 ? doSomething : somethingElse
Or, like it was said in one of the comments, use RegEx.

How to check whether a string contains a substring in JavaScript?

Closed 6 years ago.
Right now, I'm just doing the following for my Auth0 login -
if (location.hash) {
// do something
}
How can I make sure it will only do this when it includes #access_token= ?
Use indexOf like so.
if(location.hash.indexOf("#access_token=" > -1) {
// Do stuff
}
You can learn more on indexOf here.

How can I access object properties containing special characters?
(2 answers)
Closed 7 years ago.
I'm reading a JSON file through javascript. I'm having trouble getting today/_text because of the forward slash. I can get today successfully by doing: {{hours.results[0].today}}. How would I get today/_text? I've tried:
today\/_text
today/\_text
today//_text
today\\/_text
{"offset":0,"results":[{"today/_text":"Today:YES","today/_source":"/hours/1","today":"2,3,4"}]}
hours.results[0]["today/_text"] should do the trick!
hours.results[0] returns an object that has that as a key, making that the easiest way to access the property in question.

Encode URL in JavaScript
(22 answers)
Closed 8 years ago.
I want to load another page via Javascript like this
$("#resultarea").load("searchresults.php?searchstring=" + $("#searchbox").val());
in searchresults.php, a single statement
echo $_GET["searchstring"];
what I type in searchbox appears when searchresults.php is loaded except when I add space and another word, no thing appear at all. I heared it can be done by encoding or somewhat, I searched but didn't find a solution.
Try encodeURIComponent:
var encodedValue = encodeURIComponent($("#searchbox").val());
$("#resultarea").load("searchresults.php?searchstring=" + encodedValue);
