I am struggling with a simple dojo datagrid in my Zend Framework project.
I have a list of data from a mysql table that I can display, however I want users to be able to开发者_开发知识库 remove selected rows (and remove them from the db). I am using the example from Dojo DataGrid adding and deleting data. My code in my view for the datagrid looks like this.
<div dojoType="dojo.data.ItemFileReadStore" jsId="skillstore" url="<?php echo $this->baseUrl()?>/skills/hist/<?php echo $this->histid;?>"></div>
<table id="skillgrid" jsId="skills" dojoType="dojox.grid.DataGrid" store="skillstore" style="height:300px;width:500px;">
<thead>
<tr>
<th field="skillid" hidden="true"></th>
<th width="auto" field="skill">Skills</th>
</tr>
</thead>
</table>
<div>
<button dojoType="dijit.form.Button" onclick="removeRows()" >Remove Selected Row</button>
<button dojoType="dijit.form.Button" onclick="addRow()">Add another skill</button>
</div>
I've placed the code for the removing of the rows inbetween the view scripts captureStart and captureEnd tags. The code for the removeRows() looks like this.
function removeRows(e){
var items = skillsgrid.selection.getSelected();
if(items.length){
dojo.forEach(items, function(selectedItem){
if(selectedItem !== null){
skillstore.deleteItem(selectedItem);
}//endif
});//end foreach
}//end if
}
The main problem I get is that when I select a row and click the button, firebugs complains that skillstore.deleteItem is not a function. I have yet to try and remove the entry from the database.
Any pointers would be much appreciated.
These would I do.
declaring dojo.require("dojo.data.ItemFileWriteStore"); is a must. That's why firebugs complains that skillstore.deleteItem is not a function' because there is no 'deleteItem' in ItemFileReadStore but is found in 'ItemFileWriteStore'.
function removeRows(e){
var items = skillsgrid.selection.getSelected();
if(items.length){
dojo.forEach(items, function(selectedItem){
skillsgrid.store.deleteItem(selectedItem);
skillsgrid.sort(); // I did access the store of the grid directly.
});//end foreach
}//end if
}
I think all you have to do is use the jsId
attribute value as ID instead of the id
one:
var items = skills.selection.getSelected();
EDIT:
If that doesn't work, did you add the following right after the closing body
tag?
<script type="text/javascript" src="dojo.js" djConfig="parseOnLoad: true">
</script>
<script type="text/javascript">
dojo.require("dojox.grid.DataGrid");
dojo.require("dojo.data.ItemFileWriteStore");
dojo.require("dijit.form.Button");
</script>
EDIT2:
Actually, you are using a read-only store, that is the problem.
