I am looking to iterate over a list of values using javascript.
I have a list like this
Label: A Value: Test Count: 4
Label: B Value: Test2 Count: 2
Label: C Value: Test3 Count: 4
Label: D Value: Test4 Count: 1
Label: C Value: Test5 Count: 1
My goal is to pass each row into different functions based on the label. I am trying to figure out if a multidimensional array is the best way to go.
var list = [
{"Label": "A", "value": "Test", "Count": 4},
{"Label": "B", "value": "Test2", "Count": 2},
{"Label": "C", "value": "Test3", "Count": 4},
{"Label": "D", "value": "Test4", "Count": 1},
{"Label": "C", "value": "Test5", "Count": 1}
]
for(var i = 0, size = list.length; i < size ; i++){
var item = list[i];
if(matchesLabel(item)){
someFunction(item);
}
}
You get to define the matchesLabel function, it should return true if the item needs to be passed to your function.
well it's been 8 years but today you can use for ... of
const array1 = ['a', 'b', 'c'];
for (const element of array1) {
console.log(element);
}source : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of
If you would like to make it more pro, you can use this function
function exec(functionName, context, args )
{
var namespaces = functionName.split(".");
var func = namespaces.pop();
for(var i = 0; i < namespaces.length; i++) {
context = context[namespaces[i]];
}
return context[func].apply(this, args);
}
This function allows you to run it in context you want (typical scenario is window context) and pass some arguments. Hope this helps ;)
