I have created with php several javascript array which are called as follows:
pricesArray_230
pricesArray_350
...etc...
I now want to access these arrays, but I have no clue how to include the dynamic part.
My code right now, which is not working:
newPrice = pricesArray_+productId+[currentSimpleProduct][0];
Where productId is the dynamic part and represents 230, 350, or any other number.
Do any of you have an idea how to dynamically call these arrays?
If you're in the browser, and the variable is in the global scope, you can use bracket notation like:
foo = window['pricesArray_'+productId[currentSimpleProduct][0]]
To avoid eval, assuming that pricesArray_* are global variables, you can use:
window['pricesArray_' + productId][currentSimpleProduct][0]
Better yet, update your dynamically-generated code so it creates an object or array instead of variables:
var pricesArrays = {
'230': {...},
'350': {...},
// etc
}
You have to use eval:
newPrice = eval('pricesArray_' + productId)[currentSimpleProduct][0];
However, eval can be problematic, so I suggest using an object instead. This will require you to change your PHP code to output something like this:
var arrays = {
product230 : [], // array here
product350 : [] // array here, etc.
}
Then you can just use:
newPrice = arrays['product' + productId][currentSimpleProduct][0];
