Why does my code return the error "missing : after property id" in JavaScript?

Question

How is this supposed to be written so that it would actually work?

saveBuyerInfo( 
    { 'save_'+$("#textAreaXMLPostRequest").attr('name') :
    $("#textAreaXMLPostRequest").val() } );

Answer 1

You can't have an expression as the key in an object literal. Instead, create your object first:

var save = {};
save['save_' + $("#textAreaXMLPostRequest").attr('name')] = $("#textAreaXMLPostRequest").val();
saveBuyerInfo(save);
