Dynamically change the color of an HTML range element


Question

I was wondering if there is a way to dynamically change the color of an HTML range element. For example, let's say I have 3 sliders (1 for red, 1 for green, 1 for blue). I want to change the intensity of each color on the slider based on the value of the slider. An example of what I have so far is located at http://jsfiddle.net/aa5kh/

Does any body have any ideas regarding this issue? 

 

EDIT: Oops! I just noticed that the fiddle isn't there for some reason. I copied the url while I was there, but I guess I had to save it. I will recreate it. Sorry for the confusion!

My quick idea: http://jsfiddle.net/bataA/7/

The sliders change the text color.

 

Notice that I used rgb() css property which is not much compatible with old browsers. But this is the easiest I think.

 

edit: it looks like in Chrome the color only updates when I let go the mouse button, but in IE 11 it updates as the slider moves.

 

edit2: I modified the jquery so it updates the color in Chrome immediatelly as well. http://jsfiddle.net/bataA/15/

HTML :

<input type="range" id="red" min="0" max="255" />
<input type="range" id="green" min="0" max="255" />
<input type="range" id="blue" min="0" max="255" />
<input type="text" id="color" />

 

CSS :

input[type=range]::-webkit-slider-thumb {
     -moz-appearance: none;
     border-radius: 20px;
     background-color: #FFF;
     box-shadow:
        inset 0 0 16px #B2B200,
        inset 16px 0 20px #FFFF33;
     border: 2px solid #292908;
     height: 20px;
     width: 20px;
}

#color {
width: 100px;
background-color: black;
}
 

JScript :

var r = 0;
var g = 0;
var b = 0;

$('input[type=range]').each(function() {
    $(this).bind('change', function() {
        r = $('#red').val().toString(16);
        g = $('#green').val();
        b = $('#blue').val();
        
        var colorrgb = r+","+g+","+b;
        
        $("#color").css("background-color", "rgb("+colorrgb+")");
        
    });
});

If I missunderstood you and you actually want to change the sliders colors, then here it is(may look messy but works): http://jsfiddle.net/bataA/45/

 

That is very close to what I want, but I want to change the thumb within the control to that color. Thank you for your help so far. I appreciate it!

    • Microsoft's new AI tools: What "Researcher" and "Analyst" mean for your work by Paul Hill Microsoft has announced the general availability of two new reasoning AI agents called Researcher and Analyst. Both were previously available for Microsoft 365 Copilot Frontier members, but now they’re available for all Microsoft 365 Copilot license holders. Researcher is capable of multi-step research by combining OpenAI’s deep research model with Microsoft 365 Copilot’s orchestration and deep search capabilities. The Analyst agent can think like a data scientist, giving you insights in minutes from raw data. Analyst is built on OpenAI’s o3-mini. Microsoft says it can run Python to tackle the most complex data queries and you can view the code it’s running to verify its work in real time. Who it affects, and how While Frontier members have had access to these agents since April, they’ve only just been announced for general availability. The Copilot in question is not Microsoft’s free Copilot either, but the Copilot that comes as part of Microsoft 365 and includes additional features. To access it, you will have to pay for a $30 per month paid yearly subscription. Existing customers should now have access to both of these agents. While there is certainly angst in the world about the influence of AI on our jobs, Microsoft still maintains that it’s an assistant tool. These two new agents look set to benefit professionals across a range of roles including researchers and strategists, data analysts and scientists, sales and marketing teams, and anyone who just wants to summarize or synthesize information fast. The Researcher agent is helpful for gathering insights, preparing for negotiations, and assessing impacts such as the impact of tariffs on businesses. Meanwhile the Analyst agent can be used to convert raw data into actionable insights, identifying customer behaviors, and visualizing trends. It’s not all good news, Microsoft does have some limitations in place to ensure reliability of its service for all customers. The Redmond giant explains that the pre-pinned agents can run up to 25 combined queries per month - so that’s not 25 queries per agent, it’s for both together, each month. Additionally, Researcher supports 37 languages, but Analyst only supports eight, with more coming soon. Why it's happening Agents have been all the rage since the end of 2024 when figures in big tech declared that 2025 would be the year of agentic AI. Agents are capable of multi-step work and bring us closer to the goal of artificial general intelligence (AGI). These agents that Microsoft has unveiled are possible now thanks to the development of OpenAI’s deep research model and o3-mini, which also reasons. Earlier this year, Microsoft declared that it wanted to empower employees everywhere with AI agents and the release of Researcher and Analyst goes a long way in doing this. They will be beneficial for employees in many different fields and have the potential to free up a lot of time for more beneficial work. Customers in the Frontier program, Microsoft said, found these new tools to be highly effective for complex analytical work. This is great for Microsoft financially because it shows clear demand for such tools, justifying AI’s upfront development costs. These agents also help Microsoft keep up against the competition, which is also aggressively pursuing agents. What to watch for Microsoft said that its Researcher agent is much more accurate than everything that came before, thanks to the time it spends thinking about its answer. However, AI does still possess the ability, just like humans, to make mistakes. Verifying the creations of these agents is still crucial when it comes to anything mission critical. The Analyst agent’s ability to let the user see the steps and which Python code it executes is very good for transparency and can help combat errors if things ever start to go wrong with the agent’s reasoning. This could help to build trust among customers who need to use the Analyst agent and could set Microsoft’s offering apart from the competition, giving it an edge. Another thing customers should be aware of is the prompt they use matters. Microsoft tries to guide customers along with sample prompts but to get the most from these tools, users will need to know how to create effective and precise prompts. The good thing is that these bots are spoken with natural language, so it’s just a matter of being articulate and precise when you give a prompt. It will certainly be interesting to see how agents like these continue to affect employees’ job security in the future. While AI can certainly be helpful, if it develops to a point where an employer can effectively hire AI for a low cost to do the same work, then it could lead to massive displacement, with not enough new jobs for people to move into. This point has recently been elucidated by Anthropic’s CEO Dario Amodei. Source: Microsoft
