Could not delete row from array using Javascript/Jquery

You could iterate from the end, because Array#splice reduces the length of the array.

In your code, and if you splice, you have to keep the index at the same index, without incrementing.

for (var i = arr.length - 1; i >= 0; i--){
    if (arr[i]['value'] == '') {
       arr.splice(i, 1);
    }
}

arr = arr.filter(element => element.value != '')

It will skip elements since removing element will change the index, but you are not updating the value of i. Do it in reverse order to avoid such problems, i.e, end to start.

var i = arr.length;

while(i--){
    if(arr[i]['value']==''){
       arr.splice(i,1);
    }
}

Wont work because the lenth of your array is dynamically changing when you remove an element. You have to decrease the i variable. Try:

var arr = [{
        'value': '',
        'name': 'Rajeev'
      }, {
        'value': '1',
        'name': 'Raj'
      }, {
        'value': '',
        'name': 'Ram'
      }];


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

How about creating a new array, adding the items that are not '' and replacing the old with new ? Replace your loop with code below and see if it works.

var newArr = [];

for (var i = 0; i < arr.length; i++) {
    if (arr[i]['value'] !== '') {
        newArr.push(arr[i]);
    }
}
arr = newArr;

You are changing the size of the array but keep increasing the index, if you want to change array size while running a loop a suggest you use

for each (var item in arr) { 
 if(item.val==''){
       arr.splice(item ,1);
       i--;
    }

of you can do it in a more efficient way like this

array = arr.filter(function(currentChar) {
    return currentChar !== " ";
});

using lodash you can filter it out easily

the first parameter will be your array and the function returns value without ''

var fArray = _.remove(arr, function(obj) {
return ( obj.value  != '' );  });

fArray will be your desired array with value not ''
