jQuery打印变量的值 [英] jQuery print value of variable
问题描述
我是jQuery的新手,我需要一些非常简单的代码来提供帮助.因此,我有一个字符串变量,要使用listprice类在p中打印.
I am new to jQuery and I need some assistance with very simple code. So, I have a string variable that I want to print in the p with listprice class.
<script>
$(document).ready( function() {
var string = "US $257.31";
$('.listprice).append(string);
}
</script>
有什么想法可以实现吗?
Any ideas how can I achieve that?

推荐答案
您可以这样做
var string = "US $257.31";
$('.listprice').html(string);

当然,这是假定p
中没有任何内容,因为它将替换其中的所有内容.
Of course, this assumes there is nothing in the p
as it would replace everything in there.
要在p
包含内容时将其添加到单独的行上,请执行以下操作
To add it on a separate line when the p
contains content, do this
$('.listprice').append('<br />' + string);

根据您的评论
您知道我该如何使用普通的javascript吗?我觉得他们 正在阻止jquery.
Do you know how can I do that with regular javascript? I think they are blocking jquery in there.
您可以这样做
var string = "US $257.31";
var a = document.getElementsByTagName('p');
a[0].innerHTML += string;

这将找到第一个p
并添加变量string
.
This finds the first p
and adds the variable string
.
