javascript - What's wrong with this code to find heightInInches? -


after click, calculated bmi shown 0.3; expected answer 22.8

code snippet in question:

calculatebutton.addeventlistener('click', function() { var feet = feetfield.value; var inches = inchesfield.value; var heightininches = (feet * 12) + inches; bmidisplay.text = ((weightfield.value / (heightininches * heightininches)) * 703).tofixed(1); });

heightininches should equal 68, not 608. seems somehow feet (5) being multiplied 120 instead of 12 , tacking on inches (8) @ end, don't quite understand why that's happening, , why it's hiding me when step through code?

debugger shows correct values feet(5) , inches(8) in formula incorrect value assigned heightininches after calculation.

link bmi formula

i think formatted question correctly; long time listener, first time caller. i've been staring @ long... had screenshots of ui , debugger had remove images post. ok, checking out.

try adding:

var feet = parsefloat(feetfield.value); var inches = parsefloat(inchesfield.value);

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
