Hi Guys,
I have a program which converts Excel spreadsheets to Javascript and
allows interactivity. However it can't convert it to PHP, which is
obviously better for users to view (in case J/S is turned off).
How would I go about converting some of this created code (example JS
below), or is there an easier way to get PHP to do the calculations
itself? I am aware of an excel-server product but this is too expensive
and doesnt actually produce any code.
I'm not suggesting someone convert this (also as its only an example),
but the code seems quite complicated for a junior PHP person. Any
thoughts on what I could do?
Thanks
(code created by spreadsheet converter)
<script language="javascript">
var co = new Object;
function recalc_onclick(ctl) {
if (true) {
co.pA7D=eeparseFloat(document.formc.pA7D.value);calc(co);document.formc.pA7E.value=eedisplayFloat(co.pA7E);
};};
var eeisus=0;var eetrue="TRUE";var eefalse="FALSE";var eedec=".";var
eeth=",";var eedecreg=new RegExp("[.]","g");var eethreg=new
RegExp(",","g");
var row1xD2D5=new Array(4);for(var jj=0;jj<4;jj++){row1xD2D5[jj]=0};var
row1xE2E5=new Array(4);for(var
jj=0;jj<4;jj++){row1xE2E5[jj]=0};function calc(data){var
cA7D=data.pA7D;row1xD2D5[0]=(10);row1xE2E5[0]=(1);row1xD2D5[1]=(20);row1xE2E5[1]=(2);row1xD2D5[2]=(30);row1xE2E5[2]=(3);row1xD2D5[3]=(40);row1xE2E5[3]=(4);var
cA7E=(lookup3vv((cA7D),row1xD2D5,0,3,row1xE2E5,0,3));data.pA7E=cA7E;};
function myIsNaN(x){return(isNaN(x)||(typeof
x=='number'&&!isFinite(x)));};function
eeparseFloat(str){str=String(str).replace(eedecreg,".");var
res=parseFloat(str);if(isNaN(res)){return 0;}else{return
res;}};function eedisplayFloat(x){if(myIsNaN(x)){return
Number.NaN;}else{return String(x).replace(/\./g,eedec);}};function
lookup3vv(key,kvect,kfrom_start,kto_start,vvect,vfrom_,vto_){var
current=0;var from_=kfrom_start;var
to_=kto_start+1;while(true){current=(from_+to_)>>1;if(kvect[current]==key)break;if(from_==to_-1)break;if(kvect[current]<key){from_=current;}else{to_=current;}};while(current<kto_start){if(kvect[current]==kvect[current+1]){current++;}else{break;};};if(key<kvect[current])return
Number.NaN;return vvect[vfrom_+current-kfrom_start]};
