I don't know if it is possible to do this, like I have 2 js files. The first Js File:
var news_pos, about_pos, services_pos, clients_pos;
function define_pos() {
var $top_slides=$('#top_slides'),
$mid_nav=$('#mid_nav'),
$news_section=$('#section-1');
var fixed_height = $top_slides.height() + $mid_nav.height();
news_pos = fixed_height - 20;
about_pos = fixed_height + $news_section.height();
services_pos = fixed_height + $news_section.height() * 2;
clients_pos = fixed_height + $news_section.height() * 3;
}
$(document).ready(function() {
var section_news = $('#section-1'),
section_about = $('#section-2'),
section_services = $('#section-3'),
section_clients = $('#section-4');
setheight();
function setheight() {
var section_height = $(window).height() + 200;
$section_news.height(section_height);
$section_about.height(section_height);
$section_services.height(section_height);
$section_clients.height(section_height);
define_pos();
}
});
The second JS File:
$(document).ready(function() {
var nav = { '$btn1': $('#btn1'), '$btn2': $('#btn2'), '$btn3': $('#btn3'), '$btn4': $('#btn4'), '$btn5': $('#btn5'), myclick : function() { myclicked(nav.$btn1, 0); myclicked(nav.$btn2, news_pos); myclicked(nav.$btn3, about_pos); myclicked(nav.$btn4, services_pos); myclicked(nav.$btn5, clients_pos); function myclicked(j,k) { j.click(function(e) { e.preventDefault(); $('html,body').animate({scrollTop: k}, 1000); }); } // Is it right to do return{'myclick':myclick}, // how to call? seems not logical } }; // Here will not work because it say news_pos is undefined. // If I use setTimeout(nav.myclick,1000), it will works but // I want to run it right the when position is caculated. nav.myclick();
});
How do I pass the nav.myclick() function to the frist js file and put it in setheight() and under define_pos()? By the way writing codes right in stackoverflow is strange,press tab not really give you any spacing.
Right now, function setheight(){ }
is an internal function in the first $(document).ready(function(){}
. Its "scope" (visibility) is limited to inside that function.
To make it visible to everyone, you need to move it outside of $(document).ready(function(){}
.
Then, declare the first file before the second one, and functions in the second file can now use setheight()
.
To use myClick
:
Your function now is myclicked()
so you need to change that to myclick()
. Then, you can call the functions in the global scope:
function myclick(j,k){
j.click(function(e) {
e.preventDefault();
$('html,body').animate({scrollTop: k}, 1000);
setheight();
define_pos();
}
Here's one way to namespace your position functions per your "new" question in the comments. It's pure JS, not JQuery, but it's the same anyway:
var POSITIONING = {
news_pos : 0,
about_pos : 0,
services_pos : 0,
clients_pos : 0,
define_pos : function() {
var fixed_height = 100;
POSITIONING.news_pos = fixed_height; // + whatever
POSITIONING.about_pos = fixed_height; // + whatever
POSITIONING.services_pos = fixed_height; // + whatever
POSITIONING.clients_pos = fixed_height; // + whatever
},
set_height : function() {
alert(this.news_pos)
}
};
Put this in a JS file, load it before any other files that use it, and call as follows:
// For example, when the window loads...or document is ready, whatever
window.onload = function() {
POSITIONING.define_pos();
POSITIONING.set_height();
};
It's also worth noting that it looks like this could be done more efficiently with CSS using a margin or padding or something. Probably a lot easier.
