Cannot find the exact syntax of setTimeout with innerHTML as argument.

I am developing a very simple function that should allow me to display a countdown message:

var myTable=document.getElementById("myTable");
var myHTML0 = myTable.outerHTML;
var j=0;
var T=5;
for (g = 0; g<T; g++) {
      j = T-g;
      myMsg = "We have "+j+" seconds missing to go.";
      myHTML = myHTML0.substring(0,myHTML0.indexOf("We"))      +myMsg+myHTML0.substring(myHTML0.indexOf("We")+2,myHTML0.length);
***      var k = setTimeout("document.getElementById('myNote').innerHTML = myHTML",       g*1000);
      myHTML ="";
}
Unfortunately, I canno manage to spot the correct syntax of line ***. Can you suggest how? Thanx.

try this ;

var myTable=document.getElementById("myTable");
var myHTML0 = myTable.outerHTML;
var j=0;
var T=5;
for (g = 0; g<T; g++) {
      j = T-g;
      myMsg = "We have "+j+" seconds missing to go.";
      myHTML = myHTML0.substring(0,myHTML0.indexOf("We"))      +myMsg+myHTML0.substring(myHTML0.indexOf("We")+2,myHTML0.length);
***      var k = setTimeout("document.getElementById('myNote').innerHTML = '" + myHTML + "'",       g*1000);
      myHTML ="";
}

I have tried these:
1. (posted) setTimeout("document.getElementById('myNote').innerHTML = myHTML", g*1000);
2. setTimeout("document.getElementById('myNote').innerHTML = '" + myHTML + "'",       g*1000);
3. setTimeout("document.getElementById('myNote').innerHTML = "+ myHTML, g*1000);
4. setTimeout("document.getElementById('myNote').innerHTML = \'myHTML\', g*1000); (or something similar).
In case 2. it says that I've inserted a string without termination, in the other cases the editor alerts of syntax errors (3.) or returns a null value (1.), so that the table gets empty; moreover it does not support jQuery.

setTimeout("document.getElementById('myNote').innerHTML = '" + escape(myHTML) + "'",       g*1000);

"escape" does not work at all (gives unknow contents), while the other gives "string wothout termination" error as above.

It's not published yet. But I'm not sure that I need to make the string portable with escape function; I should understand instead why I get "string without termination" error even if I point the HTML code with single marks.

about your "string without termination" error :

var blabla = "some string without error";

var bloblo = "string with-----> " <------- termination error";

I can also tell you that without using quotes I get a blank content/value in the table in subject, while it works if I use the absolute syntax without timing "document.getElementById('myNote').innerHTML = myHTML;".

Escape functions returns the HTML code replacing spaces and other characters with %20 or similar: it's not what I need. Probably the code I'm using encounters troubles durign the cycle (for ex. does not refresh the k variable in time) or misses some DIV, TD, BODY or other statement or discriminates between Ucase and Lcase.
I've read on w3schools tutorial that setTimeout variables must be named with different strings, that's why I was also asking how to combine eval syntax with setTimeout syntax.
As an alternative, I could think to insert a label or another object and give it a text value equal to the string I need to display.

Could you post one generating the error?

Exactly (it's a literal translation): "Line 1, character 50, string constant without termination" or "Line 2, character 1, syntax error" in the 2 mentioned cases.

No, I want to see the string escaped :

blablabla%20blablabla
%YX

Open in new window

This is the original HTML:

<DIV style="WIDTH: 351px; HEIGHT: 25px" id=myNote align=left><TABLE style="DISPLAY: inline" border=0 cellSpacing=0 cellPadding=0 width=381>
<TBODY>
<TR>
<TD style="BORDER-BOTTOM: 1px solid; BORDER-LEFT: 1px solid; BORDER-TOP: 1px solid; BORDER-RIGHT: 1px solid" bgColor=#ff0000 width=383><FONT color=#ffffff face=Arial>Nota</FONT></TD></TR></TBODY></TABLE></DIV>

and this is the escaped HTML:

%0D%0A%3CDIV%20style%3D%22WIDTH%3A%20351px%3B%20HEIGHT%3A%2025px%22%20id%3DmyNote%20align%3Dleft%3E%3CTABLE%20style%3D%22DISPLAY%3A%20inline%22%20border%3D0%20cellSpacing%3D0%20cellPadding%3D0%20width%3D381%3E%0D%0A%3CTBODY%3E%0D%0A%3CTR%3E%0D%0A%3CTD%20style%3D%22BORDER-BOTTOM%3A%201px%20solid%3B%20BORDER-LEFT%3A%201px%20solid%3B%20BORDER-TOP%3A%201px%20solid%3B%20BORDER-RIGHT%3A%201px%20solid%22%20bgColor%3D%23ff0000%20width%3D383%3E%3CFONT%20color%3D%23ffffff%20face%3DArial%3ENota%3C/FONT%3E%3C/TD%3E%3C/TR%3E%3C/TBODY%3E%3C/TABLE%3E%3C/DIV%3E

It works! Good job; I know only have to fix a format trouble, since the new table appears padded left about 5 px from the original.
