I've changed my query parameters format from &Key=Value to /Key/Value.
Now I'm trying to parse them in the url using regex. Not sure what I'm doing wrong but this is my code
Example url path: http://localhost/MyApp/#!/Page1/SubPage1/SubPage2/Key/value-example
let re = new RegExp(`^.*/(Key)/([a-zA-Z0-9]+).*$`);
while (match = re.exec(url)) {
params[match[1]] = match[2];
}
It ends in a infinite loop
What am I doing wrong?
Instead of using regular expressions, I would suggest a more straight forward approach of using split().
var url = 'http://localhost/MyApp/#!/Page1/SubPage1/SubPage2/Key/value-example'
var keyName = 'Key'
var urlParts = url.split('/')
var keyIndex = urlParts.indexOf(keyName) // "Key" is at index #8
// Since the value appears right after the key, we can access it by increasing the index by 1
var value = urlParts[keyIndex + 1] // "value-example" is at index #9
Here is the result of the command url.split('/'):
[ 'http:',
'',
'localhost',
'MyApp',
'#!',
'Page1',
'SubPage1',
'SubPage2',
'Key',
'value-example' ]
So what we are doing is locating the index of the desired key in the array and looking at the next value - index+1.
gmodifier. The regex index is not advanced andwhilealways starts from the string start. Also, add-if there can be-in the value:let re = new RegExp(`^.*/(Key)/([a-zA-Z0-9-]+).*$`, "g");. However, if you do not expect multiple matches, just replacewhilewithif, then the regex can be used withoutg,new RegExp(`^.*/(Key)/([a-zA-Z0-9-]+).*$`).
