Have multiple select box on this page after selection of product selection in the back of the unit price column shows the corresponding prices

Can you tell me how to write?

CodePudding user response:

After selecting the incoming current control to the function, can find the current line, locate other controls in the current line

CodePudding user response:

A single select name I implemented effect but multiple select is uncertain

CodePudding user response:

If rendering a row saved a unified value (such as the entry id [data - id='XXXX']), consider circulation judge current onChange data - id corresponds to the price positioning

CodePudding user response:

$("... "). The change (function (event) {
$(this). The closest (" tr "). The find (". The unit price column element class "). The text ($(this). Val ());
});

Div elements do not have a name attribute, need to use a class for the 
 

Var moeny=document. GetElementsByClassName (" moeny "); 

Within the event using the loop variable outside need to preserve the value of each loop in closure 
for(var i=0; i(function (I) {
Class_name [I] onclick=function () {
Moeny [I] innerHTML=this. The value; 
} 
}) (I); 
}
