ui slider with text box input

Question

We have a ui slider we utilise, and it works flawlessly.

code:

jQuery(function() {
jQuery( "#slider-range-min" ).slider({
    range: "min",
    value: 1,
    step: 1000,
    min: 0,
    max: 5000000,
    slide: function( event, ui ) {
        jQuery( "#amount" ).val( "$" + ui.value );
    }
});
jQuery( "#amount" ).val( "$" + $( "#slider-range-min" ).slider( "value" ) );
});

As you can see we allow user to pick anything between 0 and 5,000,000.

Html is:

<div id="slider-range-min" style="width: 460px; float:left;margin:10px;"></div>

What I want to do is add a text input element which works in harmony with the slider, so as user slides the texy box increases, decreases whatever..

Or if the user types numbers into the input element the slider moves appropriately.

Any help please ?

Solution

You need to update the input element (like you're doing now for the #amount element) on slide:

$("#slider").slider({
    range: "min",
    value: 1,
    step: 1000,
    min: 0,
    max: 5000000,
    slide: function(event, ui) {
        $("input").val("$" + ui.value);
    }
});

Additionally, you need to bind to the change event for the input element and call the slider's value method:

$("input").change(function () {
    var value = this.value.substring(1);
    console.log(value);
    $("#slider").slider("value", parseInt(value));
});

There's no validation going on here (you must include the "$" sign for it to work). You could add some more robust input sanitation to enhance it.

Thats great Andrew, the only issue I see is user cannot type in input element and the slider moves to that priced position, until you click out of the input. I suppose could add onkeyup hey.. But great code, voted up

@422: That should work, you may have to enter a large value to see it (try $3000000 for example)

changed div to <div id="slider" style="width: 460px; float:left;margin:40px 10px;"></div> and still doesnt auto update as you type, even with larger numbers. Unless its a jsfiddle issue, will port over to html and test

You mean robust like regex? ;-) /\d+/.exec(this.value)

@AndrewWhitaker, how to remove dollar sign from input ?

[Andrew Whitaker]

@IstiaqueAhmed: Remove the dollar sign ($) from the code, as well as the substring code jsfiddle.net/VfSda
