Slider size (case 17391)

[venus]

[edited by moderator]

My RA has helped me to reprogram the slider with a Java. But how can I intergrate it in my MediaLab file?

Also, if I use the slider that you have provided in this thread, how can I change the length of it? You have described how to change the maximum and minimum, can you describe how to change the length of the slide, the anchors in two ends and how to hide the numerical value.

I have attached the Java applet that is created by my RA.

[a little bit later]

I have figured out how to add anchors to the end of the items. There are only two things that I need to sort out.

1. I followed your suggestions below and tried to show a picture in every trial, but it does not work.

2. I still don't know how to hide the nurmeric value of the slider. Here is my HTML.

By the way, I just checked the data file. What is showed is whether the participants have answered the question ("ok") but not the values that they have chosen. Have I done something wrong?

Can you please retry attaching your sample--it didn't seem to post.

Sorry. Here is the modified html. I have not modify other files.

It does not allow me to upload the html file as html. I have to change it to .txt.

I have attached the questionnaire file too.

I am trying to code something much the same as the above poster; I can manipulate the properties of the html document easily enough, but I cannot get the document to display the image stored as the background image in medialab (even if the image is pointed to 'ml.background').

The image simply will not load (and instead displays a broken link graphic). Has a workaround been developed for this, or is the only alternative to make separate html documents for each image to be used?

I have played around with things a bit, but I still cannot get the image cued in the medialab background tab to load in the html document. If I load the image directly into the html file it works fine, but doing so is far more time consuming than being able to index the medialab background.

I have attached my html code as well as a sample image; please take a look and let me know if there is something obviously wrong with it.

Here's a copy with the .que file attached. It is the same skeleton as the slider example (included in the slider zip file) without any real changes; I want to get the image display working before I change too much around.

Thanks!

Try using <ml.bg> rather than <ml.background> and see if that helps. See the user's guide for the official variable reference or online here:

I tried to do as you suggested in the quote below (using <ml.bg> rather than <ml.background>) and it still does not work. Instead, my image is appearing on the screen behind my custom slider. If I insert the name of the picture, it works fine. Any other suggestions?

Yes--MediaLab saves a copy of the HTML file that is actually presented.. I believe it will have a "temp" in the filename. Can you run it once with <ml.bg> and once with the image name and then look at the difference in the actual html files that are generated? How can zip and post them here if you like and I'll be happy to take a look.

[rkozink]

I ran it as you suggested and have attached both of the TEMP files in the zip file. The _bg file is when I used <ml.bg> and the _pic file is when the actual filename of the picture was used. Everything looks pretty much the same to me. I have it set-up so that a picture (1 of 146) is randomly selected, so the picture filenames are different between the two runs, but that should not have affected anything. Any advice for this java novice is welcomed!

Also, I opened the "slider.css" file from this thread, but couldn't find the "input name" part of the HTML text, which means I couldn't figure out what to name that slide so that MediaLab would store the input in SPSS. Where is that in the file?

[jarvis24]

The file name you would give to MediaLab would simply be continuum.htm as in the sample que file above. Note to modify the length of the slider you can just modify the code in the htm file to whatever percentage of the screen (or number of pixels) you like:

<table border="0" width="70%">

And to get rid of the value appearing at the right, change:

<input type="text" name="<ml.varname>"

to:

<input type="text" style="color:white" name="<ml.varname>"

As far as displaying images within the continuum.htm page, make sure you are using the angular brackets around the image name. If the image does not appear, replace <ml.background> with the name of a specific image in the same location to see if it appears properly. If so, attach a zipped copy of the html file and image file and I'll take a look.

Aaah...thanks. Unfortunately, I was under a time crunch and had to go with another method, but I'll definitely keep those tips in mind for when I use MediaLab in the future. And I hope someone else finds them useful in the meantime!
