我正在一个网站（使用WordPress构建）上，并且我有一个表格插件，在其中我无法通过简单地使用br标签或什至插入span来打断单词或文本，因为表格插件确实可以不允许HTML标签。
我想要实现的是打破一些th文本。
具体来说，我想这样分割文本：
安扎尔
齐默（Zimmer）
Netto-
wohnfläche
Verkaufs-
preis
瑞士法郎
我想知道如何用它来实现这一目标。
这里的表th
<th data-class="expand" class="wdtheader sort column-block sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Haus: activate to sort column ascending">Haus</th>
<th class="wdtheader sort column-wohnung sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Wohnung: activate to sort column ascending">Wohnung</th>
<th class="wdtheader sort column-anzahlzimmer sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Anzahl Zimmer: activate to sort column ascending">Anzahl Zimmer</th>
<th class="wdtheader sort column-etage sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Etage: activate to sort column ascending">Etage</th>
<th class="wdtheader sort column-nettowohnflache sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Netto-wohnfläche: activate to sort column ascending">Netto-wohnfläche</th>
<th class="wdtheader sort column-sitzplatz sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Aussenfläche: activate to sort column ascending">Aussenfläche</th>
<th class="wdtheader sort column-verkaufspreischf sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Verkaufspreis CHF: activate to sort column ascending">Verkaufspreis CHF</th>
<th class="wdtheader sort column-pdf sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="PDF: activate to sort column ascending">PDF</th>
<th class="wdtheader sort column-anfrage sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Anfrage: activate to sort column ascending">Anfrage</th>
此处的完整表格代码https://jsfiddle.net/0bkgLqx5/
答案 0 :(得分：1)
我假设表格插件为table标签或thead或th的有效父标签分配了ID。
例如：
HTML：
<table id="table">
<th data-class="expand" class="wdtheader sort column-block sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Haus: activate to sort column ascending">Haus</th>
<th class="wdtheader sort column-anzahlzimmer sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Anzahl Zimmer: activate to sort column ascending">Anzahl Zimmer</th>
<th class="wdtheader sort column-nettowohnflache sorting" style="" tabindex="0" aria-controls="table_1" rowspan="1" colspan="1" aria-label="Netto-wohnfläche: activate to sort column ascending">Netto-wohnfläche
</table>
JAVASCRIPT：
var th = document.querySelectorAll('#table th');
th.forEach(function(t) {
var text = t.textContent;
var output = text.replace(/[ |-]/g, '<br>');
console.log(output); // check your browser console for output.
t.innerHTML = output;
});
我正在使用JavaScript替换th标签内容的空格“”和连字符'-'。
替换模式“ [ |-]”将找到任何空格或破折号，并用br标记替换。
除了|“ OR”之外，您还可以尝试其他条件。
更新后的答案
根据小提琴中OP的代码。
var th = document.querySelectorAll('#table_1 thead th');
th.forEach(function(t) {
var text = t.textContent;
var output = text.replace(/[ |-]/g, '<br>');
t.innerHTML = output;

在加载表格后，使用onload方法加载JavaScript。您也可以将脚本放在页脚中。
window.onload = function() { // code goes here }
感谢 sarah 提到了onload方法。
