[英]asp.net webforms with js
如何在網絡表單中將普通js腳本與普通html代碼一起使用? 我在下面有此代碼,但是當它運行頁面上顯示的div標簽兩秒鍾時,它們便消失了。 當檢查元素時,我看到div標簽被分配了類aspNetHidden。 我怎樣才能解決這個問題?
HTML代碼:
<div class="slideshow-container">
<!-- Full-width images with number and caption text -->
<div class="mySlides fade">
<div class="numbertext">1 / 9</div>
<img src="Images/slide1.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">2 / 9</div>
<img src="Images/slide2.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">3 / 9</div>
<img src="Images/slide3.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">4 / 9</div>
<img src="Images/slide4.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">5 / 9</div>
<img src="Images/slide5.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">6 / 9</div>
<img src="Images/slide6.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">7 / 9</div>
<img src="Images/slide7.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">8 / 9</div>
<img src="Images/slide8.png" style="width:100%">
</div>
<div class="mySlides fade">
<div class="numbertext">9 / 9</div>
<img src="Images/slide9.png" style="width:100%">
</div>
js代碼:
<script type="text/javascript">
var slideIndex = 1;
showSlides(slideIndex);
// Next/previous controls
function plusSlides(n) {
showSlides(slideIndex += n);
}
// Thumbnail image controls
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
}
</script>
如果相關,css代碼:
<style>
* {box-sizing:border-box}
/* Slideshow container */
.slideshow-container {
max-width: 1000px;
position: relative;
margin: auto;
}
/* Hide the images by default */
.mySlides {
display: none;
}
/* Next & previous buttons */
.prev, .next {
cursor: pointer;
position: absolute;
top: 50%;
width: auto;
margin-top: -22px;
padding: 16px;
color: white;
font-weight: bold;
font-size: 18px;
transition: 0.6s ease;
border-radius: 0 3px 3px 0;
user-select: none;
}
/* Position the "next button" to the right */
.next {

border-radius: 3px 0 0 3px;
}
/* On hover, add a black background color with a little bit see-through */
.prev:hover, .next:hover {
background-color: rgba(0,0,0,0.8);
}
/* Caption text */
.text {

.numbertext {

}
/* The dots/bullets/indicators */

您可以將代碼段添加到content標記中,我剛剛嘗試過並且它有效。 請參考下面的代碼。 您只需使用site.master文件創建一個新的Web應用程序,然后就可以將代碼段添加到aspx文件中

好的,原來這只是一個CSS錯誤,在代碼可以運行之前,淡入淡出開始了。 只需刪除所有標簽的淡入淡出即可。
