I have an array of objects like so:

var myArray = [
    {field: 'id', operator: 'eq', value: id}, 
    {field: 'cStatus', operator: 'eq', value: cStatus}, 
    {field: 'money', operator: 'eq', value: money}
];

How do I remove a specific one based on its property?

e.g. How would I remove the array object with 'money' as the field property?

答案 1

One possibility:

myArray = myArray.filter(function( obj ) {
    return obj.field !== 'money';
});

Please note that creates a new array. Any other variables referring to the original array would not get the filtered data although you update your original variable with the new reference. Use with caution. filtermyArray

Iterate through the array, and splice out the ones you don't want. For easier use, iterate backwards so you don't have to take into account the live nature of the array:

for (var i = myArray.length - 1; i >= 0; --i) {
    if (myArray[i].field == "money") {
        myArray.splice(i,1);
    }
}
