Loop

Can anyone give me some advice on the syntax


for (var i=0; i<3; i++)

document.write("<tr>")
document.write("<td colspan=2>")
document.write("<table border=0>")
document.write("<td width=80 align=left><Font face=Arial size=2 font color=000000><b>BookTitle</b></font></td>")
document.write("<td width=180 align=center><Font face=Arial size=2 font color=FF0000><b>Book_Date</b></a></font></td>")
document.write("<td width=450><Font face=Arial size=2 font color=3300CC><b> Book_Description</b></a></font></td></table></td></tr>")

I can't get it to display the variables I have declared, can anyone help me out with it ?

I would like for it to display something like below, formatted and all.

Book A Feb AAAAAA
Book B Jan BBBBBBB
Book C Mar CCCCCC

 

You need to tell it to print the Javascript variables, such as:

document.write("<td width=80 align=left><Font face=Arial size=2 font color=000000><b>" + BookTitle + "</b></font></td>")
document.write("<td width=180 align=center><Font face=Arial size=2 font color=FF0000><b>" + Book_Date + "</b></a></font></td>")
document.write("<td width=450><Font face=Arial size=2 font color=3300CC><b>" + Book_Description + "</b></a></font></td></table></td></tr>")

 

Thank you very much vpguy for the help.

Would you mind to help me out with this following syntax also ? Thanks a million.

document.write("<td width=450><Font face=Arial size=2 font color=3300CC><A href=mailto:info@glebe.edu?subject="+ Book_title, I have read this also +">" + Book_title + "</b></a></font></td></table></td></tr>")

I am trying to have the a href automatically generate a subject base on the book title from declared variables.

The message subject should read : Book A, I have read this also. once they have click on the href Book title.

I keep getting it wrong and it is always displaying ="+ Book_title, I have read this also +" instead of an actual book title.

 

Any time you are inserting a dynamic variable, you have to stop quoting the literal text and concatenate the contents of the variable.

Therefore, the correct version of that piece of code would be:

document.write("<td width=450><Font face=Arial size=2 font color=3300CC><A href=\"mailto:info@glebe.edu?subject="+ Book_title + ", I have read this also +"\">" + Book_title + "</b></a></font></td></table></td></tr>")

Code (markup):

The \" at the beginning and ending of the href encloses it in quotes, because if a space exists it would terminate the href. Instead of \" you could also use a single quote (').

You should also ensure that the Book_title variable contains no quotes, because that would screw up the href.
