I Have an json array in the following format:
Object {field: "l0", headerText: "0-22", width: 120}
Object {field: "l1", headerText: "23-43", width: 120}
Object {field: "l2", headerText: "44-55", width: 120}
I want to delete a record on the basis of headerText value
i.e. I have value 0-22 and on the basis of this I have to delete this record. Is it possible?
Assuming your objects are wrapped in an array, like this:
var arr = [
{field: "l0", headerText: "0-22", width: 120},
{field: "l1", headerText: "23-43", width: 120},
{field: "l2", headerText: "44-55", width: 120}
];
You can do something like this:
var result = arr.filter(function(obj) {
return obj.headerText !== "0-22"; // Or whatever value you want to use
});
console.log(result);
Array.prototype.removeVal = function(name, value){
var array = $.map(this, function(v,i){
return v[name] === value ? null : v;
});
this.length = 0;
this.push.apply(this, array); //push all elements except the one we want to delete
}
var myArr = {};
myArray = [
{field: "l0", headerText: "0-22", width: 120},
{field: "l1", headerText: "0-11", width: 120},
{field: "l2", headerText: "0-33", width: 120}
];
myArray.removeVal('headerText', '0-11');
for(var i = 0; i<jsonArray.length; i++){
if(jsonArray[i]. headerText == "0-22"){
jsonArray.splice(i, 1);
}
}
Look here.
var objects = [
{field: 'l0', headerText: '0-22', width: 120},
{field: 'l1', headerText: '23-43', width: 120},
{field: 'l2', headerText: '44-55', width: 120}
];
function filterObjects(element, index) {
if (element.headerText === '0-22') {
objects.splice(index, 1);
}
}
objects.forEach(filterObjects);
console.log(objects);
Array.splice()
