I have an array of items that I'd like to loop through and apply some code to, excluding one item (the clicked-on item). I've tried using splice but I don't want to remove the array item, just skip over it. In this case, I'm trying to remove a CSS class for each item, except the excluded one.
I've tried a few methods, using splice for one which isn't what I need. I've also tried something like if (array[i] == 3 || (i - 1) = 2) { continue; else { .... } but can't seem to get that to work.
var array = ["item1", "item2", "item3"];
var i;
for (i = 0; i < items.length; i++) {
if(array[i] is the excluded one){
skip over}
else { $(items[i]).removeClass('class');
}
No error messages, just not working as expected.
Use continue
In the following example we want to exclude "item2" and fixed variable naming/reference :
var items = ["item1", "item2", "item3"]; var i; for (i = 0; i < items.length; i++) { if(items[i] === "item2"){ continue; } //$(items[i]).removeClass('class'); document.write(items[i] + "<br>"); }
are the array items the id of the elements? - if so you need the id indicator (" #
") in the code
$('#' + items[i]).removeClass('class')
EDIT - i just noticed that your array is called"array", but in the else block you refer to it as items
var items= ["item1", "item2", "item3"];
var i;
for (i = 0; i < items.length; i++) {
if(items[i] is the excluded one){
skip over}
else { $('#' + items[i]).removeClass('class');
}
I still think that there is a better way to do this - but try making the names the same and see if that works.
I think something like this is what you need:
<script type="text/javascript">
$(document).ready(function(){
$(".click").click(function(){ //When item with class click is clicked
var items = ["item1", "item2", "item3"];
var i;
var itemid = this.id;
for (i = 0; i < items.length; i++) { //go through array
if(items[i]==itemid){ //check if array item is the same as id of the class click
// Don't do anything, this is the one you clicked
}else{
$("#"+items[i]).removeClass('removeme'); // Remove class of all other with class click
}
}
});
});
</script>
<div class="item1 click removeme" id="item1">Test1</div>
<div class="item2 click removeme" id="item2">Test2</div>
<div class="item3 click removeme" id="item3">Test3</div>
Elegant way in functional programming:
const array = ["item1", "item2", "item3"];
// item to ignore
const ignore = "item2";
// use filter to keep only items which are not ignored
const newarray = array.filter((e)=> { return e !== ignore } );
// iterate over remaining
newarray.forEach((e)=> { $(e).removeClass("class"); });
