It’s really easy to do: object[“variablename”] = whatever; So for example you could have an object: var Landmarks = {} and you could add to it like so: Landmarks[“landmark” + i] = new google.maps.Icon(); and pass it that way. If you need these variables to be global (why would you?) you can access the global … Read more
It seems like a workaround but you can use attr to evaluate string. <s:set var=”myNum” value=”numConst” /> <s:set var=”number” value=”‘@xxx.CommonConstant@’+#myNum” /> <s:property value=”#attr[#number]”/> <s:if test=”#attr[#number] == 9″> do something </s:if>
I think it’s preferable to use a dictionnary if it’s possible: vars_dict = {} vars_dict[“my_variable”] = ‘Some Value’ vars_dict[“my_variable2”] = ‘Some Value’ I think it’s more pythonic.
In C#, you use dictionaries to associate values with strings.
First of all, your New-Variable invocation doesn’t do what you think it does, as you’d pipe the output of New-Variable to Where-Object instead of using the value of $Transactions | Where … as value for the variable. You need parentheses for that to work: New-Variable -Name “Transactions_$Year” -Value ($Transactions | Where {$_.Date -like “*.$Year” }) … Read more
You can only do that with bracket notation, which means you have to attach the variables to something. The global scope would be window, so that would be window[‘hello’ + newCount], but polluting the global namespace with a bunch of random properties doesn’t sound like a good idea, so using an object seems better var … Read more
Not out of the box. However, it’s easy to build by hand in many languages including JS. var operators = { ‘+’: function(a, b) { return a + b }, ‘<‘: function(a, b) { return a < b }, // … }; var op = ‘+’; alert(operators[op](10, 20)); You can use ascii-based names like plus, … Read more
Wrap them in {}: ${“file” . $i} = file($filelist[$i]); Working Example Using ${} is a way to create dynamic variables, simple example: ${‘a’ . ‘b’} = ‘hello there’; echo $ab; // hello there
This is not how you do things in Java. There are no dynamic variables in Java. Java variables have to be declared in the source code1. Depending on what you are trying to achieve, you should use an array, a List or a Map; e.g. int n[] = new int[3]; for (int i = 0; … Read more
Since ECMA-/Javascript is all about Objects and Contexts (which, are also somekind of Object), every variable is stored in a such called Variable- (or in case of a Function, Activation Object). So if you create variables like this: var a = 1, b = 2, c = 3; In the Global scope (= NO function … Read more
