Hi

am able to run using XAMPP on PC.

When i run from my board, am not getting proper data.

I mean it is not fetching the file index_1.txt.html and index_1.txt file are available in same path in sd card.

Anything wrong

Instead of using second argument with file name, is it possible to use as a function and call it in same file in below code

xhttp.open("POST", "index_1.txt", true);

Please suggest

Thanks and Regards

Hi

I have tried above example and it prints as below:

This content was requested using the POST method.

Requested at: 8/29/2018 7:46:26 AM

How Does This gets printed? Is it getting the data from "demo_post.asp".

Can anyone share the contents of "demo_post.asp" and clear understanding how it works

Thanks and Regards

Hi

My board can access post requests.

By seeing above link, it has  "xhttp.open(\"GET\", \"ajax_info.txt\", true);"

Do it need a file for taking a data.

How does it work

Actually my code will be searching a delimiter and then replace the text or value corresponding to it.

I may not be using any other file

Hi Dsonesuk,

Thanks for the Reply .It may not work as this again similar to refreshing to get the value.

Is It possible to do with HTML.

Please suggest

Hi Dsonesuk,

I have a S7G2-DK MCU board which interacts with HTML file loaded from SD card.

As mentioned above the code below has a delimiter "$$$". The code inside delimiters will be searched and replaced with a particular text or value.

var fxn = function() {
    document.getElementById('time').innerHTML = "$$$ABC1$$$";
}

"$$$ABC1$$$"  is one delimiter. Similarly it counts the number of delimiters in the html file  and updates the values based on our values assigning to replace the delimiter on html file .

The problem am facing is, whenever i refresh my web page only that particular time, the value gets updated else it will be a constant.

But i need whenever there is change in value,it should get updated without refreshing my web page.

This is my requirement and am not getting exactly how to solve this

Please suggest

Thanks and Regards

Hi Dsonesuk

Yes correct. 

I think from HTML it is updating.

But I think board is not sending updated value 

Hi Funce,

Thanks for the reply.

Actually My requirement is, I need to reload only a portion of the page like only the updating value to my html page .

Its like updating time where only seconds are updating and other part is constant.

Similar way i need to update all the values which changes dynamically every 1 second.

In the above post, i tried the code which i have posted, it updates only once whenever i refresh and not continuous.

Without refreshing i should be able to update the values .

Thanks and Regards

Hi

I have  a sample code for dynamic update of value every 1 sec.

<script>
var count = 100;
var fxn = function() {
    count++;
    document.getElementById('time').innerHTML = count;
}
setInterval(fxn, 1000);
</script>

<div id=time></div>

As in above example, i need to display dynamic values  every second .

So i tried to modify my code as below.

<br>
<input style="border:none;font-size:18pt;"  type="text"  name="$$$undefinedA1$$$" size="10" >
<script>
var fxn = function() {
    document.getElementById('time').innerHTML = "$$$ABC1$$$";
}

setInterval(fxn, 1000);
</script>
<div id=time>
</div>

In above code , i will receive the value from my board in "$$$ABC1$$$". So i should be able to update the value continuously on web browser apge.

I tried above code but doesnot work.Please suggest how to proceed.

Thanks for the reply.

I didnt get exactly what u mean to say but i tried 

                        <form action="/action_page.php" method="post" autocomplete="off" onsubmit="Validate()">
with two script files but didnt get it work.

Can you just explain once again
