javascript - 在 Javascript 中将字符串中的值提取到数组中

Question

我有这个字符串，我想将 TEXT1、TEXT2 等提取到数组 m 中。

我尝试使用正则表达式，但它不起作用。

var regex = /item\b[^>]*>(.*?)<button/g; 

var string = '<li id="reminder-1440746981190" class="new-item">TEXT1
    <button class="icon-trash delete-button" contenteditable="false"></button>
    <button class="icon-pencil edit-button" contenteditable="false"></button>
</li>
<li id="reminder-1440746983703" class="new-item">TEXT2
    <button class="icon-trash delete-button" contenteditable="false"></button>
    <button class="icon-pencil edit-button" contenteditable="false"></button>
</li>';

var m;

while ((m = regex.exec(string)) !== null) {
    if (m.index === regex.lastIndex) {
        regex.lastIndex++;
    }
}

alert(m[0]);

有什么想法吗？

你可以这样尝试:

var str = $('li').contents().filter(function(){
    return this.nodeType === 3;
}).text();

console.log(str);

<li id="reminder-1440746981190" class="new-item">TEXT1
    <button class="icon-trash delete-button" contenteditable="false"></button>
    <button class="icon-pencil edit-button" contenteditable="false"></button>
</li>
<li id="reminder-1440746983703" class="new-item">TEXT2
    <button class="icon-trash delete-button" contenteditable="false"></button>
    <button class="icon-pencil edit-button" contenteditable="false"></button>
</li>
