问题描述
我正在尝试获取每个div的rgb和索引值.在控制台中,我可以正确获取所有内容(索引和B 每个div的背景颜色).尝试将每个值添加到每个 div 中的一个 p 中,我只有每个 div 重复的最后一个值:蓝色的十六进制和数字5, 我该怎么解决?
I'm trying to get the rgb and index value of each div. In the console I get everything correctly (index and B background color for each div). Trying to add each value to a p in every div I have only the last value repeated for each div: the hex of blue and the number 5. How can I solve?
.red {
background-color:red;
}.orange {
background-color:orange;
}
.yellow {
background-color:yellow;
}
.purple {
background-color:purple;
}
.blue {
background-color:blue;
}
<div class="red"><p></p></div>
<div class="orange"><p></p></div>
<div class="yellow"><p></p></div>
<div class="purple"><p></p></div>
<div class="blue"><p></p></div>
$('div').each(function(index) {
var x = $(this).css('background-color');
$("div p").text(index+x);
console.log(index+x);
});

推荐答案
更改以下内容...
$("div p").text(index+x);
致...
$(this).find("p").text(index+x);
目前,您将再次找到所有<div>
个元素,并在每个元素中填充<p>
...这就是为什么您看到所有元素的最终值
As currently you are finding ALL <div>
elements again, and populating the <p>
in each one... that is why you're seeing the final value across all
$('div').each(function(index) {
var x = $(this).css('background-color');
$(this).find("p").text(index+x);
console.log(index+x);
});
.red {
background-color:red;
}.orange {
background-color:orange;
}
.yellow {
background-color:yellow;
}
.purple {
background-color:purple;
}
.blue {
background-color:blue;
}
