Remove from array by matching start with or regex using Jquery

Question

i'm trying to remove value from existing array. i have no idea to how to check the array for specific value and remove it. my array looks like

["Criteria.Make=scion", "Criteria.ModelName=xb", "Criteria.PriceMax=4000", "Criteria.ZipCode=23212", "Criteria.MaxDistance=50"]

i want to check if array exist Criteria.PriceMax={what ever dynamically generated value} i need to remove from the array.

i know i can use grep to remove it but i can come up with the exact need with my code

I check that value like this

$.inArray("Criteria.PriceMax",searchUrlBuilder)) > -1

won't work properly regex match will be the best but i have no idea how to do that.

thanks

Can you change your array to an object? Something like { Criteria: [ Model: 'xb', PriceMax: 4000 ]}. This way you wont need any regex hacking to find the property you need. — Rory McCrossan

My first thought would be to use Array.prototype.filter():

var filteredArray = ["Criteria.Make=scion", "Criteria.ModelName=xb", "Criteria.PriceMax=4000", "Criteria.ZipCode=23212", "Criteria.MaxDistance=50"].filter(function(a){
    return a.indexOf('Criteria.PriceMax') < 0;
});

// returns: ["Criteria.Make=scion", "Criteria.ModelName=xb", "Criteria.ZipCode=23212", "Criteria.MaxDistance=50"]

I think we posted our answers at exactly the same second!

Array.filter is just that good! :) I think that's the first time that's happened to me so far, down to the actual second...

Me too. :) First time posting at the exact second! In any case, yours is imo better since this trivial requirement does not really need a regex engine match.

i think this is more acceptable rather go for regex check. thanks David

You can use Array.filter():

var arr = ["Criteria.Make=scion", "Criteria.ModelName=xb", "Criteria.PriceMax=4000", "Criteria.ZipCode=23212", "Criteria.MaxDistance=50"];

arr = arr.filter(function(_item) {
    return !_item.match(/^Criteria\.PriceMax/);
});

returns

["Criteria.Make=scion", "Criteria.ModelName=xb", "Criteria.ZipCode=23212", "Criteria.MaxDistance=50"]
