How to eliminate a specific value from an array with the help of JavaScript

https://i.sstatic.net/7QG1J.png

I'm working with an array in JavaScript and I need to remove a specific value from it, specifically the one named "PropertyType[]". Can anyone help me figure out how to do this? I've included a picture of the array for reference. In the Newremoveurl array, I have the values.

var Newremoveurl = [];
        var Parant_name = 'PropertyType';
        $.each(Removeurl_array, function( key, value){
            var decoded_key = decodeURI(value);
            if ($.inArray(Parant_name, Newremoveurl)!='-1') {

            } 
            Newremoveurl[key]=decoded_key;
        });

Answer №1

To eliminate specific elements from your array in JavaScript, you can utilize the filter method. For an exact match, use the following code snippet:

const filteredItems = myArray.filter(item => item === "PropertyType[]")

If you want to remove values containing a particular string, you can do so with the next block of code:

const filteredItems = myArray.filter(item => item.indexOf("PropertyType[]") === -1)

Answer №2

let indexToRemove = -1;
for (let j=myArr.length; j--;) {
    if (myArr[j].includes("PropertyType")) {
        indexToRemove = j;
        break;
    }
}

If PropertyType exists, indexToRemove will be the index of the element in the array. Otherwise, it will remain -1.

To remove the element from the array:

if (indexToRemove > -1) {
    myArr.splice(indexToRemove, 1);
}

You can keep running this code until indexToRemove becomes -1, ensuring that your array is cleared of the unnecessary element.
