Example of event bubbling in JavaScript understanding

This #btncomfirmchoosecompany is a button on the bootstrap modal layer, but after clicking, the Click event is bootstrap the outer monitor hears, the effect is the modal popup layer is closed, so I do not want this click event is "passed" to the "outer" page.

Please note that the parameter E is missing from the beginning and the effect of the code does not meet my expectations.

$ ("#btnComfirmChooseCompany"). Click (function(e) {varCompanyName = ""; varCompanyID = ""; varhaschecked =false; varAllcheckbox = $ ("input[name= ' CompanyID ')");  for(vari = 0; i < allcheckbox.length; i++) {            if(allcheckbox[i].checked = =true) {haschecked=true; CompanyID= $ (Allcheckbox[i]). attr ("value")); CompanyName= $("#" +CompanyID). Parent (). Next (). text (); }        }        if(haschecked) {$ ("#txtKHName"). Val (CompanyName); $("#hidCompanyId"). Val (CompanyID); }        Else{alert ("Please choose a business!");            e. stoppropagation (); return false; }    });

The other equivalent notation

$ ("#btnComfirmChooseCompany"). Click (    comfirmchoosecompany);

function Comfirmchoosecompany (e) {    // Ibid., abbreviated }
