Hi All,

Currently I am using setinterval to update value every 1 second from server to client.

It uses cpu load, is there a way to update the value from server to client only if there is change in value and if no change,no need to update the value.

Please suggest

Hi

My current code which i tried with document.querySelector is below.

The contents in temp1 to temp8 should be visible only when correct user is logged in.

Each user has its own priority and some tabs are disabled for some users.

<form class ="language_home" action="/passwordcheck.txt" method="post">
         

                       Login: <select name='userchoice'  >

Hi

Actually i tried from https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Building_blocks/Events#Event_objects

there that function is defined .

similar way i tried with

btn.onclick = function() {

But login related part works if i directly assign a value to variable in html code but does not work when i get a value from server and click the particular tab

November 14, 2018

Hi

I tried with following example

var btn = document.querySelector('button'); function bgChange() { var rndCol = 'rgb(' + random(255) + ',' + random(255) + ',' + random(255) + ')'; document.body.style.backgroundColor = rndCol; } btn.addEventListener('click', bgChange);

but still its same.

If i give user_login=1 in html file it works fine.

Please help am not exactly getting what is the issue

November 12, 2018

Hi

4 statements i have modified as mentioned.

event is used in tabs script

<script>
function openCity(evt, cityName) {
    var i, tabcontent, tablinks;
    tabcontent = document.getElementsByClassName("tabcontent");
    for (i = 0; i < tabcontent.length; i++) {
        tabcontent[i].style.display = "none";
    }
    tablinks = document.getElementsByClassName("tablinks");
    for (i = 0; i < tablinks.length; i++) {
        tablinks[i].className = tablinks[i].className.replace(" active", "");
    }
    document.getElementById(cityName).style.display = "block";
    evt.currentTarget.className += " active";
}
</script>

But i dont understand why this function call is not execuitng

November 9, 2018

Hi

Just got some idea about json objects

<p id="demo"></p>

<script>
var myObj, x;
myObj = {"name":"John", "age":30, "car":null};
x = myObj.name;
document.getElementById("demo").innerHTML = x;
</script>

but in ajax am receiving data till now as below

if (this.readyState == 4 && this.status == 200) {
	      document.getElementById("demo2").innerHTML = this.responseText;
}

Now how to get data through ajax and json object.

My plan is to receive like below


 else if ((NX_HTTP_SERVER_GET_REQUEST == request_type) && (0 == strcmp (resource, "/tab1")))
    {
		while(i  <  number)
        {
                memset (g_str_buf, 0, sizeof(g_str_buf));
                snprintf (g_str_buf, STR_BUFFER_LEN, "%s", variable[number]);
                nx_http_server_callback_data_send (server_ptr, g_str_buf, sizeof (tab1));
                return (NX_HTTP_CALLBACK_COMPLETED);
        }
    }

How to get it , still its not clear to me

Hi

Function call is not happening.

i have 7 tabs in my code based on following example https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_tabs

Before the tabs are created i have a common section in my web page where it is accessible from any tab.I mean after this section, tabs code comes.

So before tabs code is called am calling a function

function openCity(evt, cityName)

which uses script of tabs code

but that script is not being called.

My code where function call is not executing is

function def()
{
	if(temp1 == 1)
	{
		openCity(event, 'temperature');
	}
	else if(temp2 == 1)
	{
			openCity(event, 'temperature');
	}
	else if(temp3 == 1)
	{
		openCity(event, 'temperature');
	}
	else if(temp4 == 1)
	{
		openCity(event, 'temperature');
	}
	else
	{
			func();
	}
}

In above code, temperature is a tab name which should open that tab only when the above conditions satisfy but it does not work.

Any thing wrong with my call

Hi

From above i am planning to get whole data to web page( i need to test).

Once i get whole data to web page, how to place each data in its specified location in web page

Hi

Usually i use ajax to get data every 1 sec for a particular variable as shown below and call that function using setInterval.

    <p class = "modify" id="demo11"></p>
    <script>
    function temp_val() {
      var xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
          document.getElementById("demo11").innerHTML = this.responseText;          
        }
      };
    xhttp.open("GET", "temp_val", true);
    xhttp.send();
    }

    setInterval(temp_val, 1000);
    </script>

For tab creation , i followed a example from https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_tabs

Onclick functionality if i use, then i send to server with that tab name ,..example tab1

xhttp.open("GET", "tab1", true);

and from server all the variables of that tab can be placed and receives at web page.Some thing similar to below if i use

    else if ((NX_HTTP_SERVER_GET_REQUEST == request_type) && (0 == strcmp (resource, "/tab1")))
    {
        memset (g_str_buf, 0, sizeof(g_str_buf));
        snprintf (g_str_buf, STR_BUFFER_LEN, "%d", temp_val);
        nx_http_server_callback_data_send (server_ptr, g_str_buf, sizeof (tab1));
        return (NX_HTTP_CALLBACK_COMPLETED);
    }

How to differentiate and keep each variable in required text box after reeving since i will be having a 50 to 100 variables update.

Hope you have understood my requirement

replacing alert with figure?

Not replacing alert with figure.

i need a alert with username , password and login option.

For example, if you check this example https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_alert

it displays a alert with "Hello! I am an alert box!".

Similarly i need a alert with username , password and login option.

Hi

Thanks for the info.

I got some info about addeventlistener and tried the following code.

when i click button it displays the value.

Without clicking, is it possible to load the value only once.

<!DOCTYPE html>
<html>
<body>
<button id="myBtn">Try it</button>

<p id="demo">

<script>
var x=100;
document.getElementById("myBtn").addEventListener("click", myFunction);

function myFunction() {
    document.getElementById("demo").innerHTML = x;
}
</script>

</body>
</html>

          document.getElementById("temp1").value = this.responseText; 	  
        }

Hi

I have 7 to 8 tabs in my code and interacting to server using ajax for getting dynamic data every 1 sec.

Since am requesting more data every 1 sec it is slowing down the content and it lags.

So is it possible to update only that tab which user clicks.I mean among 7 to 8 tabs user cant view all tabs at the same time.

So he views one by one based on his requirement.

So how to make only the clicked tab to get dynamic data.

Please suggest

Hi

Both the codes which were posted were helpful.

Now i get a alert saying "third button" etc.

So instead of that alert, i need to replace alert with login option as shown in figure.

Please suggest

I am trying to print the value in textbox which is selected from dropdown.

First 2 drop down values am able to print in text box as it is static value.

For third value , am getting from server.

<!DOCTYPE html>
<html>
<body>

<select onchange="Choose(this)" >
  <option value="2" >temp1</option>
  <option value="22" >temp2</option>
  <option value="temp3">temp3</option>
  <option value="temp4" >temp4</option>
</select>
<input type="text" id="answer" >


<script>
function Choose(data) {
   
    document.getElementById ("answer").value = data.value;
}

function absolute() {

      var xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) { 
	      document.getElementById("demo2").innerHTML = this.responseText;        
        }
      };
    xhttp.open("GET", "absolute", true);
    xhttp.send();
    }

Hi

when i use

it prints on both....

I need only on text box

document.getElementById("hw_maj").innerHTML = this.responseText; 
          document.getElementById("myText_hw_maj").innerHTML = this.responseText; 	

and 

 <input type="text" id="myText_hw_maj" size ="10" style="border:none;font-size:27pt;"></h3>

But if use, it prints only in textbox but occupies..i need to avoid it

        if (this.readyState == 4 && this.status == 200) {	  
          document.getElementById("hw_maj").innerHTML = this.responseText; 
          document.getElementById("hw_maj").style.visibility = "hidden";
          	  
        }
      };
    xhttp.open("GET", "hw_ver.txt", true);
    xhttp.send();
    }

    </script>
