In this post, we are going to teach you, how to Generate Barcode Using Javascript.

Now we are going to use JsBarCode Library to generate the barcode

Step 1: Insert CDN link of Js Bar Code library.

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/JsBarcode.all.min.js"></script>

Step 2: Create Input field and button to generate the barcode.

<label>Enter Text: </label>
<input type="text" class="form-control" id="barcodetext" placeholder="Type Here..."><br>
<button class="btn btn-info" type="button" onclick="generateNow();" id="generate-now">Generate</button>

Now you can see that we have created an on Click function in generate button. With the help of this function, we will generate the barcode.

Step 3: Write JavaScript code to generate the barcode.

<script type="text/javascript">
  function generateNow() {
     var text = document.getElementById("barcodetext").value;
     if(!text){
        alert('Please Enter Text');
     }else{ 
        JsBarcode("#barcode", text, {
          width: 3
        });
     }
  }
</script>

Step 4: In this step, we are showing the barcode with the help ID. You can see, in the third step, we have passed the ID (#barcode) to show the result of barcode.
