How to write logs with newline using IO.write in Ajax Truclient

Suppose you want to create your own log file, here's how to do that in Ajax Truclient using the Evaluate Javascript action from the Toolbox.

So, drag it onto your script, make sure it's inside an Action and not in vuser_init or vuser_end. It didn't work when I initially placed it inside vuser_init and I'm not sure why.

To write to a text file, basically you just need to use IO.write in this format

IO.write(filename[string], input[string], append[boolean], charset[string]);

In my case, since I want to add a timestamp and a newline after every log, here's what I used:

var currentDate = new Date();
IO.write("C:\\Data\\Logs\\logs.txt",currentDate.toLocaleString() + " >>> ",true,"UTF-8");
IO.write("C:\\Data\\Logs\\logs.txt","hello",true,"UTF-8");
IO.write("C:\\Data\\Logs\\logs.txt","\r\n",true,"UTF-8");

• On line 1 I created a date variable
• On line 2 I used toLocaleString() method to output the date time in a readable format based on the machine's default locale. In my case it's en-US. You can add parameters to this to specify a different locale. Also, make sure to escape the slashes on the path.
• On line 3 I appended my log message which says hello
• On line 4 I appended a carriage return and a newline using \r\n because sometimes \n alone doesn't work

Running it 3x produces this output. Note that it automatically creates the file if it doesn't exist BUT it doesn't create directories.

ALTERNATIVELY, you can also use the Generic API Action from the toolbox to execute the IO.write function.

Just change the category to IO, method name to write, and put it your arguments. It's essentially the same as IO.write but with less coding involved hehe

Hope this helps!

How to make an HTML modal window using Javascript and CSS

This is basically an application of this tutorial from w3schools. I've created a fiddle for it and customized mainly the CSS.

Modals are a neat way to present content in an HTML page without making it look cluttered. You can use it to contain information you don't want to be visible at all times. You increase the usability of your website by not having your user jump to a new page for small information or a form.


This is really more of a note to self haha but hope you find is useful too!
