Convert A Number To A String?
Apr 3, 2010I'm trying to write code to swap images in a list. It's going to be a star rating control that highlights stars as you hover over a star. each image in the list has an onmouseover="highlight(this)" function and a unique id of 1 - 10.
Code:
function highlight(star) {
var num = Number(star.id);
for (i = 0; i < num; i++)
[Code].....
I'm trying to convert the number 'i' used by the for loop to a string so it can be used by the getElementById() method to select the stars to be highlighted. But my intellisense is telling me there is a problem with that line. I tried
var id = String(i+1);
but this didn't work either.
what have I gotten wrong?

string to a number. For example:

Aug 2, 2010I would like to create a program which converts some letters into different ones.
1) I want 2 text areas (input and output) + "convert" button
2) if I type in the input area the letters "ea" I would like it to be converted into "a", so that If I type "cambrea" and press "submit" the output text will have "cambra".
3) if I type "e " which is (e+space) I want it to be converted into " " which is "space" example: if I type the word "spine " it should be converted into "spin , note that there is a space after "spin ".
4) If I type any vowel before "o" it should render "o", example: gambuo becomes gambo.
would this be possible? I'm not very familiar with Javascript even though I can modify it.
