Dynamically Adjust HTML Text Input Width to Content

Question

I can\'t quite find a clear answer on this, and excuse me if there is one I\'ve missed.

I want my text input widths to automatically adjust to the size of the conten

Answer 1

Use onkeypress even

see this example :http://jsfiddle.net/kevalbhatt18/yug04jau/7/

And for placeholder on load use jquery and apply placeholder size in to input

$('input').css('width',((input.getAttribute('placeholder').length + 1) * 8) + 'px');

Even you can use id instead of input this is just an example so that I used $(input)

And in css provide min-width

.form {
    border: 1px solid black;
    text-align: center;
    outline: none;
    min-width:4px;
}

If you remove all text from input box then it will take placeholder value using focusout

Example: http://jsfiddle.net/kevalbhatt18/yug04jau/8/

$("input").focusout(function(){

    if(this.value.length>0){
        this.style.width = ((this.value.length + 1) * 8) + 'px';
    }else{
      this.style.width = ((this.getAttribute('placeholder').length + 1) * 8) + 'px';
    }

});
