関数にしたいスニペットがあります。しかし、私はjavascriptを初めて使用します。明らかに、変数を渡す方法または変数を呼び出す方法に問題があります...
つまり、一言で言えば、これは機能します:http: //jsfiddle.net/kkvbz/ しかし、これは機能しません:http: //jsfiddle.net/PrtD4/
問題は、関数として必要なので、1つのバージョンを機能させる必要があることです。
完全なスニペット:
function cutandMakeslides (containerid,liperslide) {
//This is for footer slider, it rewrites 1 ul into several uls that contain 4 li max.
// get the container, useful for later too...
var container = $(containerid);
// get all available UL and LI elements...
var li_elements = container.find("> UL > LI").clone();
// remove the current content so that we can rebuild it for the slider...
container.find("> UL").remove();
// build the slider container...
var slide_container = $("<div />");
// tricky part: looping through the LI's and building each of the slides...
// first create some helpful variables...
var li_elements_per_slide = liperslide;
var li_counter = 0;
// create the first slide, with a UL to hold the LI's...
var current_li_div = $("<div />");
current_li_div.append($("<ul />"));
// loop through the LI's...
li_elements.each(function(index, element){
li_counter++;
var current_li = $(element).clone();
current_li_div.find("> UL").append(current_li);
if (li_counter % li_elements_per_slide == 0)
{
// we've hit 4 in this list, so add the slide and make
// a new one, using same code as before...
container.append(current_li_div);
current_li_div = $("<div />");
current_li_div.append($("<ul />"));
}
});
// we might have an uneven number of LI's, so we need to check for this...
if (li_counter % li_elements_per_slide != 0)
container.append(current_li_div);
} // end function cutandMakeslides
//activate function above
$(function() { cutandMakeslides(".fproductslides",3); });
問題のある部分:
function cutandMakeslides (containerid,liperslide) {
var container = $(containerid);
var li_elements_per_slide = liperslide;
}
$(function() { cutandMakeslides(".fproductslides",3); });
