Problem with dropdownbox length
- by vikitor
Hello,
I'm creating a javascript method that populates lists depending on a radio button selected previously. As it depends on animals or plants to populate it, my problem comes when I have to populate it after it's already been populated. I mean, the plants dropdownlist has 88 elements, and the animals is 888, when I try to come back from animals to plants, I get some of the animals. I know that my controller method is working properly because it returns the values I select, so the problem is the javascript method. Here is the code:
if(selector == "sOrder")
alert(document.getElementById(selector).options.length);
for (i = 0; i < document.getElementById(selector).options.length; i++) {
document.getElementById(selector).remove(i);
}
if (selector == "sOrder")
alert(document.getElementById(selector).options.length);
document.getElementById(selector).options[0] = new Option("-select-", "0", true, true);
for (i = 1; i <= data.length; i++) {
document.getElementById(selector).options[i] = new Option(data[i - 1].taxName, data[i - 1].taxRecID);}
Here is the strange thing, when I enter the method I try to erase all the elements of the dropdownlist in order to populate it afterwards. As sOrder is the same selector I had previously selected, I get the elements, the thing is that the first alert I get the proper result, 888, but in the second alert, I should get a 0 right? It shows 444, so when I populate it again it just overrides the first 88 plants and then animals till 444. What am I doing wrong?
Thank you all in advance,
Victor
