Replace Line-breaks By Spaces Using Javascript
I want to see if it's possible to block the enter key and replace it with a space. I'm also using form validation to only allow letters, numbers and some other specific characters
Solution 1:
In javascript, the line-break character is represented by \n. You could replace them by spaces in your validation function like this :
function ValidateForm(form)
{
var str
str=document.getElementById('limitedtextarea').value
str=str.replace(/[^A-Za-z0-9.-:/$ ]/g, "");
str=str.replace(/\n/g, " ");
document.getElementById('limitedtextarea').value=str
//return true;
}
Solution 2:
If you remove the onsubmit and do not have a submit button, typing enter will not submit it.
<body>
<form>
<textarea></textarea>
</form>
<script>
(function(){
var txt = document.getElementsByTagName('TEXTAREA')[0];
txt.onkeypress = function(ev){
ev = ev || window.event;
if ( ev.keyCode === 13 ){
if (window.event) {
window.event.returnValue = false;
}
if (ev && ev.preventDefault) {
ev.preventDefault();
}
txt.value += ' ';
}
};
})();
</script>
</body>
