variable name using array element, and set value

[peterpann]

using IE8
var valuedaniel = 66;
var myarray = new Array();
myarray[0] = "daniel";
alert(eval("value" + myarray[0] ) ); //66
but
eval("value" + myarray[0] ) = 77; //cannot assign to a function result

how to set ("value" + myarray[0] ) to 77 so that valuedaniel will = 77 ?
Thanks.

Hi

Supposing your question is just for your curiosity and not intend to actually use it ever :

[COLOR=orange]eval[/color][teal]([/teal][i][green]"value"[/green][/i] [teal]+[/teal] myarray[teal][[/teal][purple]0[/purple][teal]] +[/teal] [i][green]"= 77"[/green][/i][teal]);[/teal]

Thanks Feherke. Is there a better way of doing it, to avoid using eval() ?

Hi

Make value an object and use the value.daniel property :

[b]var[/b] value [teal]= {[/teal]daniel[teal]:[/teal] [purple]66[/purple][teal]};[/teal]
[b]var[/b] myarray [teal]= [];[/teal]
myarray[teal][[/teal][purple]0[/purple][teal]] =[/teal] [i][green]'daniel'[/green][/i][teal];[/teal]
[COLOR=orange]alert[/color][teal]([/teal]value[teal][[/teal]myarray[teal][[/teal][purple]0[/purple][teal]]]);[/teal]
value[teal][[/teal]myarray[teal][[/teal][purple]0[/purple][teal]]] =[/teal] [purple]77[/purple][teal];[/teal]
