jQuery print value of variable
提问by bobek
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.
我是 jQuery 的新手，我需要一些非常简单的代码的帮助。所以，我有一个字符串变量，我想用 listprice 类在 p 中打印它。
<script>
$(document).ready( function() {
var string = "US 7.31";
$('.listprice).append(string);
}
</script>
Any ideas how can I achieve that?
任何想法我怎么能做到这一点？

You could do this
你可以这样做
var string = "US 7.31";
$('.listprice').html(string);

Of course, this assumes there is nothing in the pas it would replace everything in there.
当然，这假设里面没有任何东西，p因为它会替换那里的所有东西。
To add it on a separate line when the pcontains content, do this
要在p包含内容时将其添加到单独的行中，请执行以下操作
$('.listprice').append('<br />' + string);

As per your comment
根据你的评论
Do you know how can I do that with regular javascript? I think they are blocking jquery in there.
你知道我怎么能用普通的 javascript 做到这一点吗？我认为他们在那里阻止了 jquery。
You could do this
你可以这样做
var string = "US 7.31";
var a = document.getElementsByTagName('p');
a[0].innerHTML += string;

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

You've it right except for some typos (and I added tag specifier to make the lookup bit faster):
除了一些拼写错误外，您说对了（我添加了标签说明符以使查找速度更快）：
$(document).ready( function() {
var string = "US 7.31";
$('p.listprice').append(string);
}

The above code will append US $275.31to all elements with the listpricetag.
上面的代码将附加US $275.31到所有带有listprice标签的元素。
If you want to append it only to ptags with listprice, specify $('p.listprice').append(....
如果您只想将其附加到p带有 的标签listprice，请指定$('p.listprice').append(...。
Oh, and remember to close your quotes after the identifier (listprice).
哦，请记住在标识符 ( listprice)后关闭引号。

You aren't appending (adding an element to another). You just want to change the ptext.
您没有追加（将元素添加到另一个元素）。您只想更改p文本。
$(".listprice").text(string);

You Can Also Print Your Variable Value Between String Look like...
您还可以在字符串之间打印变量值，如下所示...
var filename = $('#resume').val();
$("#msg_show").text("Your resume "+filename+" has uploaded successfully. If you wish to upload a different document, please click the “Submit your Resume” button and select your file again.");
