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);
