我正在使用html,css& amp;写一篇简短的调查问卷。 JS。我想问一个问题,然后让用户评分为1-5。
理想情况下,我希望比例尺具有响应性,因此如果你将鼠标悬停在1以上,它就会变黄。如果你将鼠标悬停在2,则会将1和2都变为黄色。如果将鼠标悬停在3以上,则会将前3个框变为黄色。你明白了。
当调查中只有一个问题时,这非常简单,但问题的数量可能是未知的(而且很长)。
我希望我可以使用相同的JS函数和css类,但是当我将鼠标悬停在页面上的1个问题上时,页面上的所有问题都会更新为黄色。这样做的最佳方式是什么,以便每个答案只能单独更新,而不是整个页面?

您可以简化代码,如下所示。
将鼠标悬停在某个元素上时,需要使用this
(指当前悬停元素)参考找到相关元素
$(function() {
var scaletext = {
1: 'SA',
2: 'A',
3: 'N',
4: 'Da',
5: 'SDa'
}
$('.scale').hover(function() {
var $this = $(this);
$this.prevAll('.scale').addBack().css('background-color', 'yellow');
$this.siblings('.scale-text').html(scaletext[$this.data('scale')]);
}, function() {
var $this = $(this);
$this.prevAll('.scale').addBack().css('background-color', '');
$this.siblings('.scale-text').html("No Rating");
});
});

您可以在jQuery中选择div的所有前一个元素。
这是您的解决方案:
var frases = ["Strongly Disagree", "Disagree", "Neutral", "Agree", "Strongly agree"];
$('.scale').hover(function() {
$(this).prevAll('.scale').css('background-color', 'yellow').end().css('background-color', 'yellow');
$(this).prevAll('.scale-text').html(frases[$(this).data('value')-1]);
}, function() {
// on mouseout, reset the background colour
$(this).prevAll('.scale').css('background-color', '').end().css('background-color', '');
$(this).prevAll('.scale-text').html("No Rating");
});

只需将#include <stdio.h>
int main(void) {
int x, y, prime;
for (x = 2; x <= 1000; x++) {
prime = 1;
for (y = 2; y * y <= x; y++) {
if (x % y == 0) {
prime = 0;
break;
}
}
if (prime == 1) {
printf("%d\n", x);
}
}
return 0;
}
等单个css类添加到所有评级元素中,然后执行以下操作:
