I need to filter an array if a key meets a certain value, for example:
data = theArray;
v开发者_StackOverflowar 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;
if i have understood your question correctly this should do it
$.each(data,function(row,key){
if(key != theKey && theColumn != theColumn){
delete data[key];
}
});
