Using JavaScript to Replace Space With Dash

February 3, 2022 Leave a Comment

To replace a space with a dash in a paragraph using JavaScript, we can use the JavaScript String replace() method.

text.replace(/ /g, '-');

Let’s say we have the following HTML:

<div id="div1">
  <p id="p1">We will update the text: <span id="span1">up to date</span></p>
</div>

If we want to change the spaces in the span “up to date” and replace them with dashes, we will use the replace method in the following JavaScript code:

var text = document.getElementById("span1").textContent.replace(/ /g, '-');
document.getElementById("span1").innerHTML = text;

Which would result in the following:

We will update the text: up-to-date

Using JavaScript to Replace Spaces with Dashes with a Click

In this example, we will let the user input any text they want, and then replace any spaces in the text with dashes(-). We will then display the new text below. If there are no spaces in the text provided, no change will occur.

Here is the HTML setup.

<p>Add text below with spaces.</p>
<input id="userVal" type="text" value="">
<input id="submitNum" type="submit" onclick="changeText()" value="View result">
<div id="results"></div>

Below is the JavaScript code which will take the user input using an onclick event and run the function below. The function will get the text using the getElementById method and textContent property, and use the replace() method on the text. We will then update the #results div using the textContent property.

Here is the JavaScript code:

function changeText() {
  var userText = document.getElementById("userVal").value;
  var replacedText = userText.replace(/ /g, '-');
  document.getElementById("results").textContent = replacedText;
}

The final code and output for this example of how to replace spaces with dashes using JavaScript is below:

Code Output:

Add text below with spaces.


Full Code:

<p>Add text below with spaces.</p>
<input id="userVal" type="text" value="">
<input id="submitNum" type="submit" onclick="changeText()" value="View result">
<div id="results"></div>

<script>

function changeText() {
  var userText = document.getElementById("userVal").value;
  var replacedText = userText.replace(/ /g, '-');
  document.getElementById("results").textContent = replacedText;
}

</script>
