I have a hidden input field that will take the value of another on keyup and I\'m trying to figure out how transform the value in the hidden field to lowercase and replace s
You can do it like this:
<script type="text/javascript">
var el = document.getElementById('identifier');
var text = el.value;
el.value = text.toLowerCase().replace(' ', '-');
</script>
or if you are using JQuery:
<script type="text/javascript">
$('identifier').value = $('identifier').value.toLowerCase().replace(' ', '-');
</script>
To switch your text to lowercase, use the JavaScript toLowerCase() method.
<script type="text/javascript">
var str="Hello World!";
document.write(str.toLowerCase());
</script>
See this Stackoverflow question on how to replace all the spaces with dashes using JavaScript.
To convert to lowercase :
var lowercase = 'This Is A Sample'.toLowerCase();
To Replace empty space:
var Replace= 'This Is A Sample'.replace(/ /g,"-");
take a look at this example
@JSbin
var lower = $('input#textFieldId').val().toLowerCase(); // to lower case
var hyp = lower.replace(/ /g,"-"); // spaces to hyphens
$('input#hiddenFieldId').val(hyp); // in hidden field
Check
This will replace all spaces with -
<script type="text/javascript">
$(document).ready(function(){
var test= $('input[name="title"]').val();
test = test.toLowerCase().replace(/ /g, '-');
$('input[name="identifier"]').val(test);
}):
</script>
