javascript variable scope in the IF statement

Question

Are variables declared and assigned in an \"if\" statement visible only within that \"if\" block or within the whole function?

Am I doing this right in the followin

Answer 1

Variables declared inside the if statement will be available outisde as long as they reside in the same function.

In your case, the best way would be to declare structure and then modify the parts of the object that differ in either case:

var structure = {
    "element" : "div",
    "attr" : {
        "class" : "actionPane"
    },
    "contains" : [{
        "element" : "a",
        "attr" : {
            "title" : "edit",
            "href" : "#",
            "class" : "edit"
        },
        "contains" : ""
    }, {
        "element" : "a",
        "attr" : {
            "title" : "delete",
            "href" : "#",
            "class" : "delete"
        },
        "contains" : ""
    }]
}

if(state != "ed") {
    // modify appropriate attrs of structure (e.g. set title and class to cancel)
}
