请教 ：JOSON数组中，有的组没有项目，要如何写判断是存项目

请问：因为数组中有的项目job_number没有对应的项目值，导致所有的都取不到，有什么办法可以取出有值的项目吗？
代码如下：
m.cJsonStr3=[var json=]+cTxt+[;]
m.oJs3=CREATEOBJECT("MSScriptControl.ScriptControl")
m.oJs3.Language="jscript"
m.oJs3.addCode(m.cJsonStr3)   
m.oSon3=m.oJs3.CodeObject.json.result.list
FOR EACH m.SubItem IN m.oSon3
    &&?m.SubItem.name &&这大概就是你要的值了
    l_user1=m.SubItem.name
    l_mobile1=m.SubItem.mobile
    l_userid=m.SubItem.userid
    IF TYPE('m.SubItem.job_number')='O'
       l_job_number=m.SubItem.job_number
    ELSE
       l_job_number=''
    ENDIF
ENDFOR

附cTxt字符
