I need to filter an array if a key meets a certain value, for example:
data = theArray;
var theColumn = "thc012";
var theVal = 4;
data = $.filter(data, theColumn, theVal );
And then the result would be all the array items that match theColumn = theVal ;
I am already using the jQuery Library so if any jQuery functions help, use them.
Thanks
Javascript objects are key-value pairs. You can use them. Like so:
var data = {
"cars": ["Honda", "Toyota", "Subaru"],
"planes": ["Boeing", "Airbus", "Mig"]
};
var key = "cars";
data[key]; // All cars
key = "planes";
data[key]; // All planes
I think you're looking for the grep method: jQuery.grep
Then just supply it with a function that checks if theColumn = theKey;
key is set in a variable. This means it I do el.theColumn, with theColumn being the variable with the key name, and el, being the array, it in fact looks for the key name theColumn, instead of what the value of the variable theColumn is, if this makes sense?
if i have understood your question correctly this should do it
$.each(data,function(row,key){
if(key != theKey && theColumn != theColumn){
delete data[key];
}
});
