javascript - How to have a range to two input boxes where it will be divided after... -


i have 2 input fields automatically divides first input second one.

first input field:

<input type="text" name="myname1" id="1" value="1000.00" onkeyup="getvalues(1)" size="10">

second input field:

<input type="text" name="myname2" id="2" value="26" onkeyup="getvalues(2)" size="10">

output:

<input type="text" id="main" name="myoutput" size="5" value=38.46>

and script:

<script language="javascript">     function getvalues(val){         var numval1=parsefloat(document.getelementbyid("1").value,10);         var numval2=parsefloat(document.getelementbyid("2").value,10);         var totalvalue = numval1 / numval2;          document.getelementbyid("main").value = totalvalue.tofixed(2);     } </script>

how can add min/max range both input fields range accepted on first input field 200-1000, , second input field 1-26. alert cool if value not within specified range.

thanks!!!

do simple interval-bound check:

function getvalues(val){ var numval1=parsefloat(document.getelementbyid("1").value,10); var numval2=parsefloat(document.getelementbyid("2").value,10); var totalvalue = numval1 / numval2;  if(numval1 >= 200 && numval1 <= 1000){   document.getelementbyid("1").style.bordercolor='red'; }else{   document.getelementbyid("1").style.bordercolor=''; } if(numval2>= 1&& numval2 <= 26){   document.getelementbyid("2").style.bordercolor='red'; }else{   document.getelementbyid("2").style.bordercolor=''; } document.getelementbyid("main").value = totalvalue.tofixed(2); }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
