Select Data Target

Hi,

I trying to create a selection list to a variable called fck, but indepent of the selection made it bring the results of previous variables:

Here is the code:

'<h3> Dimensionamento de Seções</h3>'
'<hr />
'<h4>Materiais</h4>'
'<h5>Coeficientes de Ponderação</h5>'
'Coeficiente de minoração do aço
γ_s = ? 
'Coeficiente de minoração do concreto
γ_c = ? 
'<h4>Concreto</h4>'
#pre
'<p>Escolha o fck - 
'<select data-target="fck">
'<option value=15>C15</option>
'<option value=18>C18</option>
'<option value=20>C20</option>
'<option value=25>C25</option>
'<option value=30>C30</option>
'<option value=35>C35</option>
'<option value=40>C40</option>
'<option value=45>C45</option>
'<option value=50>C50</option>
'<option value=55>C55</option>
'<option value=60>C60</option>
'<option value=65>C65</option>
'<option value=70>C70</option>
'<option value=75>C75</option>
'<option value=80>C80</option>
'<option value=85>C85</option>
'<option value=90>C90</option>
'</select></p>
#post
'<table id="fck">
'<tr><td>'f_ck = ? '</td></tr>
'</table>
f_cd = f_ck/γ_c
α_v2 = 1 - f_ck/250
#if f_ck ≤ 50
f_ctm = 0.3*f_ck^(2/3)
#else
f_ctm = 2.12*ln(1 + 0.11*f_ck)
#end if

Someone can tell me what i’m doing wrong?

Best regards

Hi, I am glad you have managed. 😃 Thank you for your questions. You are so kind!

1. I have not enabled sponsorship yet but I can do it if there is any interest.
2. Any contributors are welcomed. There are a lot of things that need to be done, that require different skills. The general method is to clone the repository make changes and place pull requests. But it is good to coordinate the work. I can open a discussion for that purpose: https://github.com/Proektsoftbg/Calcpad/discussions.
3. There are some external forums currently:

• in Reddit: https://www.reddit.com/r/calcpad
• in Quora: https://calcpad.quora.com
• github has also some nice forum like features. We can use the discussions or wiki pages for that purpose. I can also set up a forum inside the calcpad official website: https://calcpad.eu FYO there is a blog as well: https://calcpad.blog

You’d better also put the id in the immediately enlosing element, which is td in your case:

#show
'<table>
'<tr><td id="fck">'f_ck = ? '</td></tr>
'</table>
#post

You can even just use a paragraph element. If you wan’t to hide it so that that the user would not put any other values add also display:none style:

#show
'<p id="fck" style="display:none;">'f_ck = ? '</p>
#post
