Hello guys,i Have 2 tables,A parent table & a child table.

the parent table is linked to child table, i have two columns Total amount & total weight in PARENT TABLE,

the CHILD TABLE contains the individual amounts & weights.

so what i want is the sum of the individual amounts & weights from CHILD TABLE to be displayed in PARENT TABLE. also,

please can somebody help me with the code ?

the problem that im facing is THE PARENT TABLE has different set of AMOUNTS & WEIGHTS!

the below is the code of what i tried,but the problem is,each parent has a child,as there r many parents & child, when i run this,the Total amount & total weight will return the sum of all the parents & child present in the grid.


 var theTotal = 0;
 $(".child_amount_grid").each(function () {
    theTotal += ($(this).val() == "" || isNaN($(this).val()) || $(this).val() == undefined) ? 0 : parseInt($(this).val());

 });
 $('.parent_totalamt_grid').html(theTotal);

theTotal = 0;
 $(".child_weight_grid").each(function () {
     theTotal += ($(this).val() == "" || isNaN($(this).val()) || $(this).val() == undefined) ? 0 : parseInt($(this).val());
 });
 $('.parent_totalwt_grid').html(theTotal);

推荐答案

.child_amount_grid)。each(function(){
theTotal + =(
(".child_amount_grid").each(function () { theTotal += (


this )。val()== || isNaN(
(this).val() == "" || isNaN(


this )。val())||
(this).val()) ||
