cfgrid实现CRUD

      转眼2个多星期过去了，学到的还只是些皮毛，今天本来想自己写一个CRUD练练，写起来还真是费劲啊，跟当初学java的时候有一拼，咳，上网找吧，发现一个标签cfgrid，接着搜到了好多的有关的代码（都是老外写的，中文的资料啥时能多一点啊），找到一经典代码：

test.cfm:

<cfwindow initshow="true" center="true"
            width="430" height="340" title="Artists">

<cfform>
    <cfgrid name="artists"
            format="html"
            pagesize="10"
            striperows="yes"
            selectmode="edit"
            delete="yes"
            bind="cfc:artists.getArtists({cfgridpage},
                                        {cfgridpagesize},
                                        {cfgridsortcolumn},
                                        {cfgridsortdirection})"
            onchange="cfc:artists.editArtist({cfgridaction},
                                            {cfgridrow},
                                            {cfgridchanged})">
        <cfgridcolumn name="is" display="false" />
        <cfgridcolumn name="lastname" header="Last Name" width="100"/>
        <cfgridcolumn name="firstname" header="First Name" width="100"/>
        <cfgridcolumn name="email" header="E-Mail" width="200"/>
    </cfgrid>
</cfform>

</cfwindow>

 artists.cfc

<cfcomponent output="false">


    <cfset THIS.dsn="cfartgallery">

            and ARGUMENTS.gridsortdir NEQ "">
            ORDER BY #ARGUMENTS.gridsortcolumn# #ARGUMENTS.gridsortdir#
        </cfif>
        </cfquery>

        <!--- And return it as a grid structure --->
        <cfreturn QueryConvertForGrid(artists,

</cfcomponent>

 虽然也有其它的版本，但是这个最权威，因为它是ColdFusion之父Ben Forta写的，呵呵。
