Javascript jQuery$（this）.html（text）不'；I don’我不在客栈工作

我正在编写一个脚本，可以更改文本以显示用户选择的语言。
实际上，我是在页面加载时做的，默认情况下使用ita语言。它适用于所有div，除了innested div。我不明白为什么，它不会引发异常，所以try-catch都不能告诉我为什么。这是我的剧本：

var pattEng1 = /\[lang='eng']/g;
var pattEng2 = /\[.{1}lang='eng']/g;
var pattIta1 = /\[lang='ita']/g;
var pattIta2 = /\[.{1}lang='ita']/g;
var langs = ["ita","eng"];
var texts = new Array();
var i = 0, j;
var textToEdit, startPosEng, endPosEng;

$("div").each(function(){
    texts.push($(this).html());
    textToEdit =  texts[i];
    startPosEng = textToEdit.search(pattEng1) + 12;
    endPosEng = textToEdit.search(pattEng2) - startPosEng;
    textToEdit = textToEdit.replace(textToEdit.substr(startPosEng,endPosEng),"");
    try {
        $(this).html(textToEdit);
    }
    catch(err) {
       $("#demo").html(err.message);
    }
    j = 0;
    while(j < langs.length) {
        textToEdit = $(this).html();
        textToEdit = textToEdit.replace("[lang='"+langs[j]+"']", "");
        textToEdit = textToEdit.replace("[\/lang='"+langs[j]+"']", "")
        $(this).html(textToEdit);
        j++;
    }
    i++;
});

var pattEng1=/\[lang='eng']/g；
var pattEng2=/\[.{1}lang='eng']/g；
var pattIta1=/\[lang='ita']/g；
var pattIta2=/\[.{1}lang='ita']/g；
变量langs=[“ita”，“eng”]；
var text=新数组（）；
var i=0，j；
var textToEdit、startPosEng、endPosEng；
$（“div”）。每个（函数（）{
text.push（$（this.html（））；
textToEdit=文本[i]；
startPosEng=textToEdit.search（模式1）+12；
endPosEng=textToEdit.search（模式2）-startPosEng；
textToEdit=textToEdit.replace（textToEdit.substr（startposen，endPosEng），“”）；
试一试{
$（this.html（textToEdit）；

捕捉（错误）{

我尝试在innested div中的“replace”之后“alert”textToEdit变量，它工作了，它替换了它必须替换的内容，但它没有将其放入$（this）.html（textToEdit）。

CHAPTER ONE - 01<br>
THE BOY WHO LIVED<br>
Mr. and Mrs. Dursley, of number four, Privet Drive, were proud to say
that they were perfectly normal, thank you very much. They were the last
people you'd expect to be involved in anything strange or mysterious,
because they just didn't hold with such nonsense.<br>
Mr. Dursley was the director of a firm called Grunnings, which made
drills. He was a big, beefy man with hardly any neck, although he did
have a very large mustache. Mrs. Dursley was thin and blonde and had
nearly twice the usual amount of neck, which came in very useful as she
spent so much of her time craning over garden fences, spying on the
neighbors. The Dursleys had a small son called Dudley and in their
opinion there was no finer boy anywhere.<br>
The Dursleys had everything they wanted, but they also had a secret, and
their greatest fear was that somebody would discover it. They didn't
think they could bear it if anyone found out about the Potters. Mrs.
Potter was Mrs. Dursley's sister, but they hadn't met for several years;
in fact, Mrs. Dursley pretended she didn't have a sister, because her
sister and her good-for-nothing husband were as unDursleyish as it was
possible to be. The Dursleys shuddered to think what the neighbors would
say if the Potters arrived in the street. The Dursleys knew that the
Potters had a small son, too, but they had never even seen him. This boy
was another good reason for keeping the Potters away; they didn't want
Dudley mixing with a child like that.[/lang='eng']

CAPITOLO UNO - 01<br>
IL RAGAZZO SOPRAVVISSUTO<br>
Mr e Mrs Dursley, di Privet Drive numero 4, erano orgogliosi di poter affermare che erano
perfettamente normali e grazie tante. Erano le ultime persone al mondo da cui aspettarsi che
avessero a che fare con cose strane o misteriose, perché sciocchezze del genere proprio non le approvavano.<br>
Mr Dursley era direttore di una ditta di nome Grunnings, che fabbricava trapani. Era un uomo
corpulento, nerboruto, quasi senza collo e con un grosso paio di baffi. Mrs Dursley era magra,
bionda e con un collo quasi due volte più lungo del normale, il che le tornava assai utile, dato che
passava gran parte del tempo ad allungarlo oltre la siepe del giardino per spiare i vicini.
I Dursley avevano un figlioletto di nome Dudley e secondo loro non esisteva al mondo un bambino più bello.[/lang='ita']
