比较encodeURI和encodeURIComponent

    var t="#0#%E5%B1%9E%E5%9C%B0%E5%88%86%E7%B1%BB" 
    decodeURI(t)
    "#0#属地分类"
    var m=decodeURI(t)
    undefined
    encodeURIComponent(m)
    "%230%23%E5%B1%9E%E5%9C%B0%E5%88%86%E7%B1%BB"
    encodeURIComponent(m+"980")
    "%230%23%E5%B1%9E%E5%9C%B0%E5%88%86%E7%B1%BB980"
    encodeURIComponent(m+"980abc")
    "%230%23%E5%B1%9E%E5%9C%B0%E5%88%86%E7%B1%BB980abc"
    decodeURIComponent("%230%23%E5%B1%9E%E5%9C%B0%E5%88%86%E7%B1%BB980abc")
    "#0#属地分类980abc"
    encodeURIComponent(m+"980%abc")
    "%230%23%E5%B1%9E%E5%9C%B0%E5%88%86%E7%B1%BB980%25abc"
    decodeURIComponent("%230%23%E5%B1%9E%E5%9C%B0%E5%88%86%E7%B1%BB980%25abc")
    "#0#属地分类980%abc"
