Fascinating problem regarding JavaScript object literals

Below is a code snippet you can try:

var myObject = {"COL_SEQ":16,"SERVICE_CD":0.000000,"SERVICE_ID":0.000000,"COL_NAME":"","COL_OPTION":"nosort nofilter","COL_CLASS":"REMOVE_PATIENT","COL_TYPE":"","COL_LABEL":"","COL_OPTION":""};

alert(myObject.COL_SEQ);
alert(myObject.COL_OPTION);
alert(myObject.COL_CLASS);

When running this code, the 2nd alert should display "nosort nofilter". However, it appears blank instead of showing the expected message.

Here is a link to a live example for testing purposes: http://jsfiddle.net/zD7Wm/

Any ideas on why this might be happening?

Answer №1

The issue lies in having a duplicate (empty) COL_OPTION at the end of the object, which replaces your initial one.

To resolve this, simply remove the redundant second instance and your code will function correctly:

var oObject = {"COL_SEQ":16,"SERVICE_CD":0.000000,"SERVICE_ID":0.000000,"COL_NAME":"","COL_OPTION":"nosort nofilter","COL_CLASS":"REMOVE_PATIENT","COL_TYPE":"","COL_LABEL":""};
