string manipulation & PDF file
over 7 years ago
First of all, thank you for trying to help me. It should be simple , but I think I am missing something
I have an HTML file that it’s used to produce a pdf file and gets date from a screen selection
It is about string manipulation (extraction a substring that starts with “[“ from a string and displaying the result )
Example instead of Van5[15] it’s supposed to display Van
The HTML file is:
<html> <head> <script>>// <![CDATA[ function extract() { var room=[RoomName] return str.substring(0, str.lastIndexOf("[")); } document.getElementById("demo").innerHTML = extract(); // ]]></script> </head> <body onload="extract()"> <table> <tr> <td colspan="2" style="text-align:center; font-size:80;color:White; font-family:Verdana; font-weight:bold;border:1px solid Black;"> T</td> </tr> <tr> <td colspan="2" style="text-align:center; font-size:80; font-family:Verdana; font-weight:bold;border:1px solid Black;"> </td> </tr> <tr> <td colspan="2" style="text-align:center; font-size:60; font-family:Verdana; font-weight:bold;border:1px solid Black;"> [RoomName] <p id="demo"></p> </td> </tr> <tr> <td colspan="2" style="text-align:center; font-size:29;font-family:Verdana;font-weight:bold;border:1px solid Black;"> [ClassName] </td> </tr> <tr> <td colspan="2" style="text-align:center; font-size:20;font-family:Verdana;font-weight:bold;border:1px solid Black;"> [Date] </td> </tr> </table> </body> </html>The output(pdf file ) looks like this:
---------------------------------------------------------------------------------
The <script>
var room=Van5 [15];
return str.substring(0, str.lastIndexOf("["));
}
document.getElementById("demo").innerHTML = extract();
should display Van5
(Note: data for [RoomName], [ClassName], [Date] are variables that comes from a previous screen)

no need of <.![CDATA[ and function extract() should be function extract() { var str=[RoomName]; return str.substring(0, str.lastIndexOf("["));
