Add a break after a specific word with Javascript

Question

I am working on a website (built in WordPress) and I have a table plugin where I cannot break words or text by simply using the br tag or even insert span because the table plugin does not allowes HTML Tags.

What I want to achieve is to break some th texts.

In the specific I would like to split this text like this:

Anzahl
Zimmer

Netto-
wohnfläche

Verkaufs-
preis CHF

I would like to know how can I achieve this with it.

Here the table 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>

Answer 1

I assume that the table plugin assigns id to the table tag or thead or valid parent tag for th .

As an example:

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;

});

I am using JavaScript to replace the space " " and hyphens '-' of th tags content.

The replace pattern " [ |-] " will find any spaces or dashes and replace it with br tag.

You can play around with other conditions except | " OR ".

UPDATED ANSWER

According to OP's code from fiddle.

 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; });

use onload method to load JavaScript after your table has been loaded. You can place the script in footer too.

window.onload = function() { // code goes here }

Thanks sarah for mentioning onload method.
