html_string "<span class=\"verse\"><strong>1<\/strong>\u00a0hello world how are you?,<span class=\"trans\" title=\"\u00a0Greek brothers.\">t<\/span> I am fine thank you.<\/span><span class=\"verse\"><strong>2<\/strong>\u00a0this world is very bad.<\/span><span class=\"verse\"><strong>3<\/strong>\u00aall me are good,<\/span>"

我只想提取具有类verse的跨度内的文本，并且它不应该包含具有类trans的跨度文本。

结果必须是数组形式。

从上面的字符串我必须得到这样的结果

["\u00a0hello world how are you? I am fine thank you","\u00a0this world is very bad.","\u00aall me are good,"]

谢谢

这个怎么样：

var html_string = "<span class=\"verse\">"
                    + "<strong>1</strong>\u00a0hello world how are you?,"
                    + "<span class=\"trans\" title=\"\u00a0Greek brothers.\">t<\/span> "
                    + "I am fine thank you."
                + "</span>"
                + "<span class=\"verse\">"
                    + "<strong>2</strong>\u00a0this world is very bad."
                + "</span>"
                + "<span class=\"verse\">"
                    + "<strong>3<\/strong>\u00aall me are good,"
                + "</span>";

// Build up the DOM in a hidden element we can parse through
var $html = $('<div>',{html:html_string}).hide().appendTo('body');

// loop through each verse    
$html.find('.verse').each(function(i,e){
    // grab the verse, but first delete any span.trans
    var verse = $(e).find('span.trans').remove().end().text();
    // console.log(verse);
});
// remove the html from the DOM
$html.remove();

您应该能够在不将其添加到 DOM 的情况下循环它，但由于某种原因，我无法让它工作。可能是因为太晚了，或者我的手指在晚上罢工。无论哪种方式，如果有人找到一种不附加它的方法，请发布，我会投票。
