var array = [{
name: "Mango",
weight: "15gm"
}, {
name: "Banana",
weight: "10gm"
}, {
name: "Apple",
weight: "15gm"
}, {
name: "Grapes",
weight: "5gm"
}, {
name: "Banana",
weight: "15gm"
}];
I want to remove all other than Banana.
See here .
array.filter(function(x) {
return x.name == "Banana";
});
So given this input:
[{"name":"Mango","weight":"15gm"},{"name":"Banana","weight":"10gm"},{"name":"Apple","weight":"15gm"},{"name":"Grapes","weight":"5gm"},{"name":"Banana","weight":"15gm"}]
We get this output:
[{"name":"Banana","weight":"10gm"},{"name":"Banana","weight":"15gm"}]
In above array when i remove array element using splice method my array length decremented by 1 so I have to consider index i. Following is a code to remove such objects.
for(var i=0;i<array.length;i++){
if(array[i].name !== "Banana"){
array.splice(i,1);
i--;
}
}
