Help required with addition in a Client Script

arnabbose · ‎07-14-2016

Hi Experts,

I am trying to do a wright% validation on my form with below Client Script. If total weight is more or less than 100% ; alert should throw.

function onSubmit() {

//Type appropriate comment here, and begin script below

process_req_type();

function process_req_type(){

var w1=g_form.getValue('weight');

alert(w1);

var w2=g_form.getValue('weight_1');

alert(w2);

var w3=g_form.getValue('weight_3');

var w4=g_form.getValue('weight_4');

var w5=g_form.getValue('weight_5');

var w6=g_form.getValue('weight_6');

var w7=g_form.getValue('weight_7');

var w8=g_form.getValue('weight_8');

var w9=g_form.getValue('weight_9');

var w10=g_form.getValue('weight_10');

var w = (w1+w2+w3+w4+w5+w6+w7+w8+w9+w10);

alert(w);

if ( w == 100)

{

g_form.setValue ('total_weight', Math.round(w));

}

else {

alert ("Total weight% cannot be less or more than 100% , please re-enter values");

g_form.setValue ('total_weight', "");

g_form.setValue ('weight', "");

g_form.setValue ('weight_1', "");

g_form.setValue ('weight_3', "");

g_form.setValue ('weight_4', "");

g_form.setValue ('weight_5', "");

g_form.setValue ('weight_6', "");

g_form.setValue ('weight_7', "");

g_form.setValue ('weight_8', "");

g_form.setValue ('weight_9', "");

g_form.setValue ('weight_10', "");

return false;

}

The issue is that the addition is not happening and w is stroing concatenated values from variables w1 , w2, w3 etc.

For example, I put 50 in w 1 and w2 -- instead of 100 , w holds 5050.

Please help me resolve this!!!

Often these are the mistakes developers usually do. If we convert

If we try to convert space into integer, we will get NaN. If any of those weight fields are blank, you will get NaN value. So, you need to do some empty check or NaN check. Once you parsed to integers using parseInt function, do NaN checks and if they are NaN, make them 0.

var w1 = parseInt(g_form.getValue('weight'), 10);

if(isNaN(w1))

w1 = 0;

var w2 = parseInt(g_form.getValue('weight_1'), 10);

if(isNaN(w2))

w2 = 0;

Did it finally work.. I tried the same in the test instance and see the same problem..

Created two column with the type of Integer.. On submit in the client script I gave in the below

var w1=g_form.getValue('weight1');

alert(w1);

var w2=g_form.getValue('weight2');

alert(w2);

var total = parseInt(w1) + parseInt(w2);

alert("The added sum is "+total);

or

the parseInt suggested by Chuck..

I get the Nan. Even though I have a value filled in the weight1 and Weight2 field

Yes It DID ...sCRIPT bELOW :-

function onSubmit() {

//Type appropriate comment here, and begin script below

process_req_type();

function process_req_type(){

var w1 = parseInt(g_form.getValue('weight'), 10);

//alert(w1);

if(isNaN(w1))

w1 = 0;

var w2 = parseInt(g_form.getValue('weight_1'), 10);

//alert(w2);

if(isNaN(w2))

w2 = 0;

var w3 = parseInt(g_form.getValue('weight_3'), 10);

if(isNaN(w3))

w3 = 0;

var w4 = parseInt(g_form.getValue('weight_4'), 10);

if(isNaN(w4))

w4 = 0;

var w5 = parseInt(g_form.getValue('weight_5'), 10);

if(isNaN(w5))

w5 = 0;

var w6 = parseInt(g_form.getValue('weight_6'), 10);

if(isNaN(w6))

w6 = 0;

var w7 = parseInt(g_form.getValue('weight_7'), 10);

if(isNaN(w7))

w7 = 0;

var w8 = parseInt(g_form.getValue('weight_8'), 10);

if(isNaN(w8))

w8 = 0;

//alert(w8);

var w9 = parseInt(g_form.getValue('weight_9'), 10);

if(isNaN(w9))

w9 = 0;

var w10 = parseInt(g_form.getValue('weight_10'), 10);

if(isNaN(w10))

w10 = 0;

//var w = parseInt(w1)+parseInt(w2)+parseInt(w3)+parseInt(w4)+parseInt(w5)+parseInt(w6)+parseInt(w7)+parseInt(w8)+parseInt(w9)+parseInt(w10);

//var w = parseInt(w1+w2+w3+w4+w5+w6+w7+w8+w9+w10);

var w = w1+w2+w3+w4+w5+w6+w7+w8+w9+w10;

//alert(w);
