Yep, Javascript works in view on iPad
I have been playing around with a different way to view labs (but we still
don't have a way to call J from hview yet, do we? :) )
Here is the script for what I have done so far. Apologies to anyone who
actually knows how to code. :)
cocurrent 'uxjlab'
require '~addons/ide/ios/labs.ijs'
require '~addons/labs/labsx/lab.ijs'
clear ''
jx 85 NB. out of range to initialize labs
CATCOLOR=: ;:'OrangeRed LightSalmon Gold Lime DodgerBlue Fuchsia' NB. Category
colors
CATCLASS=:~.LABCATS_jlab_
LABNAMES=:(([:>:':'i.~])}.])each LABTITLES_jlab_
LABNUMS=:": each <"0@i.@#LABTITLES_jlab_
CSS=:JS=:HTML=:''
CATSTYLE=:;(<'[name='),each CATCLASS,each(<'] { color:'),each CATCOLOR,each(<';
} ')
BUTTONSTYLE=:;(<'button { display:inline; color:'),each CATCOLOR,each(<';
font-size:1em; text-shadow:1px 1px 2px #000000; } .catButton { font-size:1.3em;
opacity:1; display:inline; }')
GROUPSTYLE=:;(<'div[name='),each CATCLASS ,each(<'] {width:70%; display:none }
div[name='),each CATCLASS ,each(<'] .on {width:70%; display:inline }
div[name=core] {width:70%; display:inline-block }')
CSS=:'<style> ',CATSTYLE,GROUPSTYLE,BUTTONSTYLE,' </style>'
CATBUTTONS=: ;('<button onclick="showLabs(this)" class="catButton" name="',,&'"
id="',,&'">',,&'</button>')each CATCLASS
LABBUTTONS=: (('" id="',,&'" >',,&'</button>') each) each (LABCATS_jlab_
</.LABNAMES)
LABBUTTONS=: (LABCATS_jlab_ </.LABCATS_jlab_)(,each) each LABBUTTONS
LABBUTTONS=:('<button onclick="labText(this)" width=150px; class="labButton"
name="'&,each)each LABBUTTONS
LABBUTTONS=:((<'">'),,&(<'</div>'))each LABBUTTONS
LABBUTTONS=:;;(('<div name="'&,)each CATCLASS); each LABBUTTONS
HTML=: CATBUTTONS,LABBUTTONS
JS=: ' function showLabs(t) { var dl
=document.getElementsByTagName("div").length; for(var i=0;i<dl;i++) { var x=
document.getElementsByTagName("div")[i];
if(x.getAttribute("name")===t.getAttribute("name")) {
x.style.display="inline-block";} else {x.style.display="none";};};}'
JS=: JS,' function labText(t){ alert(t.getAttribute("id")+ "\n Enter: jx "+
labNum(t)+ " in text entry.");}'
JS=: JS,' function labNum(t){ var bl
=document.getElementsByTagName("button").length; for(var i=0;i<bl;i++) { var x=
document.getElementsByTagName("button")[i];
if(x.getAttribute("id")===t.getAttribute("id")) { return i-6;}};}'NB. subtract
6 to account for 6 category buttons
JS=:'<script>',JS,'</script>'
jux=: 3 : 0
jy '<html><head>',CSS,'</head><body>',JS,HTML,'</body></html>'
)
jux_z_=:jux_uxjlab_
