查找并替换整个html本身中出现的字符串
[英]Find and replace occurrence of string in whole html itself
问题描述
Assume 
假设
<html>
<head>....</head>
<body>
.
. // Occurrences are here
.
</body>
</html>
I do 我做
$(function()

$('html').html() = $('html').html().replace(/strToFind/g,'somethingElse');
});
in head, but it does't work. 在脑海中，但它不起作用。 How I do to find and replace all occurrence of string in html document itself (not store in variable)? 如何查找和替换html文档本身中所有出现的字符串（而不存储在变量中）？

.html() is a function that returns the HTML, you can't assign to it. .html()是一个返回HTML的函数，您无法为其分配。 If you want to change the HTML of an object in jQuery, you put the new HTML as a parameter to the function: 如果要在jQuery中更改对象的HTML，请将新的HTML作为函数的参数：
$('html').html($('html').html().replace(/strToFind/g,'somethingElse'));

$('html').html() would return the html string , but won't set it. $('html').html()将返回html字符串，但不会设置它。
You can use this function 您可以使用此功能
function rep_all()
{
var str = $('html').html();
str.replace('strtofind','strtoreplace');
$('html').html(str);
}

.html() is something which writes on the html page it is not like variable so you can't assign anythig to it. .html()是写在html页面上的东西，它不像变量，因此您不能为其分配任何thig。 you need to put the value inside it.like this: 您需要将值放在其中。像这样：
$('html').html( $('html').html().replace(/strToFind/g,'somethingElse'));

It's been answered that the .html() is not assignable, you would have to pass the replaced content as a parameter. 有人回答说.html()是不可分配的，您必须将替换后的内容作为参数传递。
Just to point out, it is very uncommon to replace the whole page's html content. 只是指出，替换整个页面的html内容非常少见。
As you defined that the contents to be replaced are inside the body , you should at least (still not good) target only the body : 当您定义要替换的内容在body内部时，您至少（仍然不好）应仅针对body ：
$('body').html($('body').html().replace(/strToFind/g,'somethingElse'))
