I have array of regex pattern, i want to check the url which matches the regex and use it. please let me know the best way to do it.
The code i have written is something like this.
var a = ['^\/(.*)\/product_(.*)','(.*)cat_(.*)'];
var result = a.exec("/Duracell-Coppertop-Alkaline-AA-24-Pack/product_385346");
Expected:
when i use a.exec it should parse the url "/Duracell-Coppertop-Alkaline-AA-24-Pack/product_385346"
and give results.
Iterate over the regexes like this:
var a = ['^\/(.*)\/product_(.*)','(.*)cat_(.*)'];
var result = [];
for (var i = 0; i < a.length; i++) {
result.push(RegExp(a[i]).exec("/Duracell-Coppertop-Alkaline-AA-24-Pack/product_385346"));
}
All matches are then stored in result.
result[0] is a array with matches from the regex in a at index 0, result[1] --> a[1], etc. If there are no results from the regex, result[x] will be null.
Instead of pushing the regex result to a array, you could also work on the result directly:
for (var i = 0; i < a.length; i++) {
var currentResult = RegExp(a[i]).exec("/Duracell-Coppertop-Alkaline-AA-24-Pack/product_385346");
// Do stuff with currentResult here.
}
You can loop over your regex array:
var a = [/^\/(.*)\/product_(.*)/, /(.*)cat_(.*)/];
var results = [];
for (var i = 0; i < a.length; i++) {
var result = a[i].exec("/Duracell-Coppertop-Alkaline-AA-24-Pack/product_385346");
results.push(result);
}
console.log(results);
