hi guys
I have a grid like this
basic-dup-grid.png
Is it possible that for each column (Product and Time)if a value appears more than once then
make the first value visible and hide the other dupilcate values in the cell (dont show it on UI)
In my code
I have a renderer like

var prodPlaceHolder = {};
function productrenderer(value, meta) {
        if( !prodPlaceHolder[value] ) {  // check if it already exists (return null if not)            
        prodPlaceHolder[value] = true;
        meta.tdCls = meta.record.data.product + "-color";
        //alert(meta.tdCls);
        return value;
    }
    else {
        return  '';  // Instead of removing the value i want to keep it but not show it on UI, make it hide or invisible.
    }
}

 {header: "Product", width: 200, dataIndex: 'product', sortable: true,renderer:productrenderer},

 so that finally i see
basic-dup-grid-result.png
Any ideas?
 Thanks

If you use jQuery there are two methods you can apply to the objects.  You can use hide() and that will remove the element from the DOM.  Or you can use fade() and that will render the element invisible, but keep its placeholder, not changing the alignment of the other elements.  Based on your example, it looks like fade() would be the choice you want.

Please post the HTML markup that renders your grid and I'll be glad to show you the jQuery that can be applied to an event to cause the fade() to occur.

Hi Here is your solution:

<table id="tbl1" width="200px" border="1">
<tr>
    <th>PRODUCT
    </th>
    <th>TIME
    </th>
    <tr>
        <td>Mango
        </td>
        <td>May
        </td>
    </tr>
    <tr>
        <td>Mango
        </td>
        <td>Jun
        </td>
    </tr>
    <tr>
        <td>Pineapple
        </td>
        <td>Aug
        </td>
    </tr>
    <tr>
        <td>Grape
        </td>
        <td>Dec
        </td>
    </tr>
    <tr>
        <td>Apple
        </td>
        <td>Jan
        </td>
    </tr>
    <tr>
        <td>Pineapple
        </td>
        <td>Jan
        </td>
    </tr>
    <tr>
        <td>Mango
        </td>
        <td>Jun
        </td>
    </tr>
</tr>    
</table>

<br/>
<input type="button" id="btnFilter" value="Filter records" />

Open in new window


And your jquery function is:

$(function(){
    $('#btnFilter').click(function(){       
        $('#tbl1').find('tr').find('td:first').each(function(index){
            if(index > 0)
            {
                for(var c = index -1; c >= 0; c --)
                {                    
                    if($(this).html() == $('#tbl1').find('tr').find('td:first').eq(c).html())
                    {
                        $(this).css('color', 'red');                        
                    }
                }
            }
        });        
    });
});

Open in new window


You can use any jquery function for functionality. Hope this solves your query.

Can not we combine Ext.js code and jQuery code ?

After rendering all in browser, it is just simple HTML table.
and I have given you the logic to apply filter to HTML table.

It should work, if table structure is same which you provided.

If not, then please share your rendered updated HTML table structure. for this also we just need to update logic for selecting TRs and TDs.

I am new to Ext-js and not sure if we can combine Ext.js and jquery code.
I am not using html anywhere, all my code is in javascript.
Here is the complete code
Ext.create('Ext.data.Store', {
    storeId:'productStore',
    fields:['product','time', 'sales'],
    groupField: 'department',
    data:[
        {product:"apple", time:"april", sales:"1"},    
        {product:"mango", time:"may", sales:"1-5"},  
        {product:"pineapple", time:"june", sales:"10-15"},
        {product:"grape", time:"july", sales:"15-30"},
        {product:"apple", time:"dec", sales:"15-30"}, 
        {product:"pineapple", time:"may", sales:"30-35"},
        {product:"apple", time:"jan", sales:"2-5"}
        
                               
    ]
});


var prodPlaceHolder = {};
function productrenderer(value, meta) {
        if( !prodPlaceHolder[value] ) {  // check if it already exists (return null if not)            
        prodPlaceHolder[value] = true;
        meta.tdCls = meta.record.data.product + "-color";
        //alert(meta.tdCls);
        return value;
    }
    else {
        return  '';  // Instead of removing the value i want to keep it but not show it on UI, make it hide or invisible.
    }
}

Ext.create('Ext.form.Panel',{
    layout : {
		type : 'hbox',
		align: 'left',
		pack: 'center'
        
	}, 
    items: [       
	{
        id:'myGrid',
        xtype : 'grid',       
        title: 'Product Analysis',
        store: Ext.data.StoreManager.lookup('productStore'),       
        autoHeight: true,        
        columns: [
            {header: "Product", width: 79, dataIndex: 'product', renderer:productrenderer},
            {header: "time", width: 100, dataIndex: 'time',  sortable: true },
            {header: "sales", width: 100, dataIndex: 'sales', sortable: true}              
        ],
    height:410,
    //width:400,
    // split: true,
    // region: 'south',
    renderTo: Ext.getBody(), 
        
        
    	}
    ]
    }

Open in new window

Thanks

Hi royjayd,

I asked for rendered HTML table structure.
I mean this code is fine, but if you share how it looks like on browser and the layout of table after displaying on browser, it would be great help.

hi Mrunal-

You just have to run this code in Sencha Fiddle : https://fiddle.sencha.com/#fiddle/m0

Code:
Ext.create('Ext.data.Store', {
    storeId:'productStore',
    fields:['product','time', 'sales'],
    groupField: 'department',
    data:[
        {product:"apple",     time:"april", sales:"1"},    
        {product:"mango",     time:"may",   sales:"1-5"},  
        {product:"pineapple", time:"june",  sales:"10-15"},
        {product:"grape",     time:"july",  sales:"15-30"},
        {product:"apple",     time:"dec",   sales:"15-30"}, 
        {product:"pineapple", time:"may",   sales:"30-35"},
        {product:"apple",     time:"jan",   sales:"2-5"}
        
                               
    ]
});


var prodPlaceHolder = {};
function productrenderer(value, meta) {
        if( !prodPlaceHolder[value] ) {  // check if it already exists (return null if not)            
        prodPlaceHolder[value] = true;
        meta.tdCls = meta.record.data.product + "-color";
        //alert(meta.tdCls);
        return value;
    }
    else {
        return  '';  // Instead of removing the value i want to keep it but not show it on UI, make it hide or invisible.
    }
}

Ext.create('Ext.form.Panel',{
    layout : {
		type : 'hbox',
		align: 'left',
		pack: 'center'
        
	}, 
    items: [       
	{
        id:'myGrid',
        xtype : 'grid',       
        title: 'Product / currency/ tenor Analysis',
         store: Ext.data.StoreManager.lookup('productStore'),          
        autoHeight: true,        
        columns: [
            {header: "Product", width: 79, dataIndex: 'product', renderer:productrenderer},
            {header: "time", width: 100, dataIndex: 'time',  sortable: true },
            {header: "sales", width: 100, dataIndex: 'sales', sortable: true}              
        ],
    height:410,
    //width:400,
    // split: true,
    // region: 'south',
    renderTo: Ext.getBody()
        
        
    	}
    ]
    }
)

Open in new window


And you will see the table created by ext-js
