jQuery的查找和替换文本,没有元素ID [英] jquery find and replace text, without element id
问题描述
我遇到的唯一问题是找到一个文本字符串,它没有附加到一个元素一个ID。否则,这很容易。
我正在尝试这样的事情:
<$ (),$ b $(this).html(this.html()。replace('Original Text','New Text'));
});
不能很好地工作。 >
另外,如果我有几个单词或短语可供查找和替换,那么这会如何影响用户浏览器的速度/处理能力呢?它是一个内存猪?
Takpar,你的代码也可以。它似乎停止了一些其他的工作,但只有我拉动物品。例如,当我使用 .ajax()
时。不知道为什么,但这就是我碰到的原因。
$ b $ b $ p $ <$ p $ ($(this).children()。length == 0){
$(this).text($($) (this).text()。replace('Subject:','Name:'));
}
});
我遇到的唯一问题是替换在加载页面后加载的文本。
我有一些显示服务器数据的javascript函数,但是只有在页面加载了所有元素之后。例如,用户从启动事件的下拉列表中选择一个值,以从数据库加载产品列表。
我将这些产品的一部分格式化为:
格兰尼史密斯苹果
价格:x.xx每磅
营养成分....
我只想找到一个替换单词Price:,并且可能将其替换为Cost: 。
但是,正如我所提到的,该数据尚未加载。
是我必须忍受的限制吗?
I'm playing around with finding and replacing text.
The only problem I'm having is finding a text string, that is not attached to an element with an ID. Otherwise, it would be easy.
I'm trying something like this:
$("*").each(function () {
$(this).html(this.html().replace('Original Text','New Text'));
});
Not working too well.
Anyone run into this before?
Also, if I have several words or phrases to find and replace, how does that affect the speed/processing power of the user's browser? Is it a memory hog?
Takpar, your code works too. It seems to stop a few other things from working, but only items I'm pulling dynamically. For example, when I'm using .ajax()
. Not sure why, but that's why I ran into. I'll test more.
On a related topic, Gumbo's code works:
$("*").each(function () {
if ($(this).children().length == 0) {
$(this).text($(this).text().replace('Subject:','Name:'));
}
});
The only thing I'm running into issues with is replacing text that is loaded after the page loads.
I do have some javascript functions that are displaying data from the server, but only after the page has loaded all elements. For example, a user selects a value from a dropdown that initiates an event to load a list of products from the database.
I format some of those products like this:
Granny Smith Apples
Price: x.xx per pound
Nutritional facts....
I will only want to find a replace the word "Price:", and possibly replace it with "Cost:".
But as I mentioned, that data has not been loaded yet.
Is a limit I have to live with?
