I have a sharepoint column named AllLinks in which im storing array as:

[{"AllLinks":"Link9","LinkURL":""},   
 {"AllLinks":"Link6","LinkURL":""}]

How to check if a value exists in an array of objects and if a match is found, delete the key value pair.

For example if the value Link6 matches, delete the entry pletely from the array using javascript/jquery. I tried with:

var newA = data.d.results.filter(function (item) return item.AllLinks !== x;});  

but item.AllLinks again returns the plete array itself

as AllLinks is a column in my sharepoint list.

• 1 Note that nothing about this is JSON. I changed the title, description and tags for you. – Rory McCrossan Commented Aug 17, 2017 at 10:35
• But in many json validators it es out as valid json.Is it really not json and just array of objects? – saumya bhargava Commented Aug 17, 2017 at 10:48

You can use filter function:

var a = [{"AllLinks":"Link9","LinkURL":"http://www.Link9."},{"AllLinks":"Link6","LinkURL":"http://www.Link6."}]

var newA = a.filter(function (item) {
    return item.AllLinks !== "Link6";
});

You can do this in such an easy way here:

var jsonArry = [{"AllLinks":"Link9","LinkURL":"http://www.Link9."},{"AllLinks":"Link6","LinkURL":"http://www.Link6."}];

var value = "Link6";

for(var i=0; i<jsonArry.length; i++){
   if(jsonArry[i].AllLinks === value){
        jsonArry.splice(i,1);
   }
}

console.log(JSON.stringify(jsonArry));

If you are sure that the value key is unique then add a break keyword inside the for loop within if after you delete the object so as to prevent unnecessary loops like this,

for(var i=0; i<jsonArry.length; i++){
   if(jsonArry[i].AllLinks === value){
       jsonArry.splice(i,1);
       break;
   }
}
