JS controls the checkbox implementation to list the checked items.

This is what it looks like by default.

When I select the last two items and click "selected", the items that I have selected are displayed, but those that are not selected are not displayed. Click "all" to list all items.

After I click selected

Click <input id = "button2" type = "button" value = "selected" onclick = "yxz ();"/> </TD> JS control: gridview_zc is the ID of the help point field gridview <SCRIPT type = "text/JavaScript"> function yxz () {// view the selected if (! Document. all. gridview_zc) {return;} for (I = 1; I <document. all. gridview_zc.rows.length; I ++) {var cb = document. all. gridview_zc.rows (I ). cells (0 ). children (0); var ROW = document. all. gridview_zc.rows (I); If (! CB. Checked) {row. style. Display = "NONE" ;}}</SCRIPT>

:

Click All assets:

<Input id = "button3" type = "button" value = "all assets" onclick = "QB (); "/> <SCRIPT type =" text/JavaScript "> function QB () {// view all if (! Document. all. gridview_zc) {return;} for (I = 1; I <document. all. gridview_zc.rows.length; I ++) {var ROW = document. all. gridview_zc.rows (I); row. style. display = "Block" ;}}</SCRIPT>
