remove string element from javascript array
arrays, javascript, jquery
Solution
From https://stackoverflow.com/a/3955096/711129:
Array.prototype.remove= function(){
var what, a= arguments, L= a.length, ax;
while(L && this.length){
what= a[--L];
while((ax= this.indexOf(what))!= -1){
this.splice(ax, 1);
}
}
return this;
}
var ary = ['three', 'seven', 'eleven'];
ary.remove('seven')
or, making it a global function:
function removeA(arr){
var what, a= arguments, L= a.length, ax;
while(L> 1 && arr.length){
what= a[--L];
while((ax= arr.indexOf(what))!= -1){
arr.splice(ax, 1);
}
}
return arr;
}
var ary= ['three','seven','eleven'];
removeA(ary,'seven')
You have to make a function yourself. You can either loop over the array and remove the element from there, or have this function do it for you. Either way, it is not a standard JS feature.
