javascript - jQuery Each Loop Not updating HTML in variable -

-

i have variable html stores html:

<tr class="odd">     <td class="charge1">0</td>     <td class="nc1">0</td> </tr> <tr class="even">     <td class="charge2">0</td>     <td class="nc2">0</td> </tr> <tr class="odd">     <td class="charge3">250</td>     <td class="nc3">0</td> </tr>

basically need add values td class starting charge values td class starting nc , replace value in td class starting nc sum. values in both td's in each row change, code needs dynamic. example, resulting hmtl in variable should be:

<tr class="odd">     <td class="charge1">0</td>     <td class="nc1">0</td> </tr> <tr class="even">     <td class="charge2">0</td>     <td class="nc2">0</td> </tr> <tr class="odd">     <td class="charge3">250</td>     <td class="nc3">250</td> </tr>

in example, row changes third row. td starting class nc shows 250 instead of original 0.

i have use variable html later in code updated td information if did change.

this code have, it's not working:

var html = $('#chargetable').html(); console.log(html); $('[class*=nc]', html).each(function(){     var ncamount = $(this).html();     var chargeamount = $(this).parents('tr').find('[class*=charge]').html();     var totalnc = parsefloat(chargeamount) + parsefloat(ncamount);     $(this).html(totalnc);     console.log(chargeamount + ' ' + ncamount + ' ' + totalnc); }); console.log(html);

this results of console's log:

<tr class="odd">     <td class="charge1">0</td>     <td class="nc1">0</td> </tr> <tr class="even">     <td class="charge2">0</td>     <td class="nc2">0</td> </tr> <tr class="odd">     <td class="charge3">250</td>     <td class="nc3">0</td> </tr>  0 0 0 0 0 0 250 0 250  <tr class="odd">     <td class="charge1">0</td>     <td class="nc1">0</td> </tr> <tr class="even">     <td class="charge2">0</td>     <td class="nc2">0</td> </tr> <tr class="odd">     <td class="charge3">250</td>     <td class="nc3">0</td> </tr>

the html variable isn't being updated, can't life of me figure out how update, short of splitting variable, replacing td class nc, , recreating html variable on each iteration. i'm thinking there's got better way this.

any appreciated.

the problem code cannot use html variable in line $('[class*=nc]', html) second parameter used define scope in jquery searches selector. so, document,parent.document(if iframe etc..)

if need original dom can use jquery .clone() store original dom this

//if require original code later clone  var htmlclone = $('#chargetable').clone().html(); console.log(htmlclone); $('#chargetable [class*=nc]').each(function(){     var ncamount = $(this).html();     var chargeamount = $(this).parents('tr').find('[class*=charge]').html();     var totalnc = parsefloat(chargeamount) + parsefloat(ncamount);     $(this).html(totalnc);     console.log(chargeamount + ' ' + ncamount + ' ' + totalnc); }); console.log(htmlclone);
