我是网络开发的新手我有一个关于如何创建图像计数器以及如何设置图案的问题。
我现在有一个占位符文本,现在是01/05的风格,但我想知道我怎么能真正把它变成一个具有相同风格的计数器。任何帮助将非常感激。另外,我正在使用Bootstrap。
<script>
var slideIndex = 1;
showDivs(slideIndex);
function plusDivs(n) {
showDivs(slideIndex += n);
}
function showDivs(n) {
var i;
var x = document.getElementsByClassName("mySlides");
if (n > x.length) {slideIndex = 1}
if (n < 1) {slideIndex = x.length} ;
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
x[slideIndex-1].style.display = "block";
}
</script>
<div class="container">
<div class="col-md-6 col-xs-12">

答案 0 :(得分:1)
在showDivs
内,您可以设置innerHTML
元素的slides
:
var counter = document.getElementsByClassName("slides")[0];
counter.innerHTML = "<b>" + slideIndex + "/" + x.length + "</b>";
