如何在循环中调用函数

Question

I need to call a function in a loop.

I have the following code....

do {
    var name = prompt("Enter name:");

    if (!isNaN(age) && name != null && name != "") {
        names[i] = name;
    }
    loop = confirm("Add new name?");

    i++;
    // at this place I want to call the function
    // addnew(document.getElementById("newtable")"; so when someone clicks cancel in the confirm box the javascript creates a dynamic table from the array names
} while (loop);​

Anyone knows how I can call the function addnew?

Answer 1

I'm guessing that you want the function called when the Confirm answers yes and terminate the loop when it doesn't which could be implemented like this:

while(true) {
    var name = prompt("Enter name:");
    if (!name) {
        break;
    }

    if (!isNaN(age)) {
        names[i] = name;

    }


    if (!confirm("Add new name?")) {
        break;
    }

    i++;
    // at this place I want to call the function
    addnew(document.getElementById("newtable")); 
}

Are you looking to do something like this:

var name,
names = [];

function coolFunc(names) {
    console.log(names);
}

do {
    var name = prompt("Enter name:");

    if (name != null && name != "") {
        names.push(name);
    }
    loop = confirm("Add new name?");

//  if you want to handle the names one-by-one as you get them, then you could call 
//  your function here, otherwise call it when you exit the loop as below

} while (loop);

coolFunc(names);

I removed the test for age because there isn't anything in what you posted to indicate where that's coming from and so was throwing an error, so you'd need to work that back in as appropriate, and i didn't really seem necessary but was also throwing an error.
