[英]Why does my variable keep resetting itself?
I have an image slider that I built for my website, and I have it set to slide every 3 seconds (will be slower after diagnostics, but I don't like waiting 10 seconds to see what's wrong). 我有一个为网站构建的图像滑块,并且将其设置为每3秒滑动一次(诊断后速度会变慢,但我不希望等待10秒才能看到问题所在)。 I also have it set so that before it auto-slides, it checks if the toSlide
variable is set to 1 (default) or not. 我还设置了它,以便在它自动滑动之前,它检查toSlide
变量是否设置为1(默认值)。 When the user clicks on a next/previous link or to a certain slide, it sets toSlide
to 0. 当用户点击下一个/前一个链接或在一定滑动,它设置toSlide
为0。
My problem is that it auto-slides again, then sets toSlide
back to 1, and I can't figure out why. 我的问题是它会再次自动滑动,然后将toSlide
设置回1,我不知道为什么。 Could anybody help me please? 有人可以帮我吗?
You can see the HTML on my site , and here is the Javascript: 您可以在我的网站上看到HTML,这是Javascript:
//Featured Work Image Slider
// sC = sliderCount
// sA = slideAmount
// pH = pictureHeight
// sT = slideTime
var sC = 1;
var pH = 364;
var sT = 364
var toSlide = 1;
function slide(ms) {
$('#featured-box li').stop().animate({'top':sA},ms);
$('.sN').css({color:'#598dbe'});
$('#sN'+sC).css({color:'#464646'});
$('#fD > div').fadeOut(ms,function(){
$(this).css({display:'none'});
});
$('#fD-'+sC).fadeIn(ms,function(){
$('#fD-'+sC).css({display:'block'});
});
console.log(toSlide);
}
function autoSlide(ms) {
if(sC < 4) {
sC++;
sA = -(sC - 1) * pH;
} else {
sC = 1;
sA = 0;
}
slide(ms);
if(toSlide = 1) {
setTimeout ( "autoSlide(sT)", 3000 );
}
}
$(document).ready(function() {
setTimeout ( "autoSlide(sT)", 3000 );
$('#sL').click(function(){
toSlide = 0;
if(sC > 1) {
sC--;
sA = -(sC - 1) * pH;
} else {
sC = 4;
sA = -3 * pH;
}
slide(sT);
return false;
});
$('#sN').click(function(){
toSlide = 0;
if(sC < 4) {
sC++;
sA = -(sC - 1) * pH;
} else {
sC = 1;
sA = 0;
}
slide(sT);
return false;
});
$('.sN').click(function(){
toSlide = 0;
var sNid = this.id.split('sN');
sC = sNid[1];
sA = -(sC - 1) * pH;
slide(sT);
return false;
});
});
if (toSlide = 1) {
This is an assignment not a comparison. 这是一项分配,而非比较。 You want to do: 您想做:
if (toSlide === 1) {
The altered full function: 更改后的完整功能:
function autoSlide(ms) {
if(sC < 4) {
sC++;
sA = -(sC - 1) * pH;
} else {
sC = 1;
sA = 0;
}
slide(ms);
if(toSlide === 1) {
setTimeout ( "autoSlide(sT)", 3000 );
}
}
if(toSlide = 1) should be if(toSlide == 1) if(toSlide = 1)应该是if(toSlide == 1)
