How to add a check all function with checkboxes in columns

Hi,

I have encountered an issue on having a "check all" function on my dataTable.
I have noticed that on the 1st page when my shown entry = 10 the entries on the 11th onward returns a null HTML element and I could not set is property to change it from checked=false to checked= true and vice versa.
Can anyone have any inputs on this?
Thank you very much.

    Use the $ API method:

    [code]
    oTable.$('tr input').attr( 'checked', true );
    [/code]

    Thanks Allan for you prompt reply.

    But I noticed also that my concept is not what I need.
    I figured out on checking only the visible rows, how ever when I tried to turn the pages, my "check all" input textbox is not changing its attribute, and leaving the checked inputs from the previous page I checked is still checked, I want only to apply the function on the visible or current page of the table.

    Have you done something like this before?
    Thanks in advanced.

    Or rather is there any way I could determine that the paging buttons are clicked? so that I can check/uncheck the "check all" input checked=false.

    Thank you very much.

    Did you use my method above, or just a straight jQuery selector? DataTables removes elements from the page, thus a normal jQuery request will not work.

    Also if you are using server-side processing, then the other pages don't even exist yet, so that needs to be taken into account.

    Hi Allan,

    Thank you for your response.
    I am doing this with the code below, since I am not using server-side processing
    I am using this where i = number of total records all in all.
    [code]$( "input[id=chkDel"+i+"]" ).attr('checked', true);[/code]

    If I am going to use server-side processing, I encountered issues setting the "check all" function using input checkbox (which does not checked the visible checkboxes).
    Or do you have any other suggestions in mind?

    Thank you very much.

    And if you try the DataTables $ API method as I suggested above, does that work?:

    [code]
    table.$( "input[id=chkDel"+i+"]" ).attr('checked', true);
    [/code]

    Hi Allan,

    It worked, however, I noticed that when the page is changed, the "check all" checkbox is still checked though none of the checkboxes on the column is checked.

    Best regards

    Hi Allan,

    To give you a better picture on this.
    I am trying to add a checkbox column to mark a row or entry to determine which to delete.
    and my delete button is only enabled whenever any of the checkbox is checked.

    Also, the reason I did not use server-side processing is because I have the 2nd column where I am displaying 3 fields from the database table, which I am extracting only the 1st character of the 3rd field.

    Regards

    I also tried to use this code:
    [code]{"fnRender": function ( oObj ) {
    return ""+ oObj.aData[1] +', '+ oObj.aData[2] + ' ' + oObj.aData[3] +"";},
    "aTargets": [ 1 ]
    }[/code]

    But I cannot figure out how to have the checkbox inserted:
    What I used is the code below to have the checkboxes is:
    [code]
    [/code]

    Thank you very much

    Hi,

    I've come up of a concept to achieve what I am working by using server-side processing, and use [code]
    {"fnRender": function (oObj) {
    return "";
    },
    "aTargets": [0]
    },
    [/code]
    However, I am having issue on getting the original value of id field since oObj.aData[0] is returning the rendered value :
    [code]
    BUSA, MELISSA GUARINO(data from db)
    [/code]

    Does any have can give me some inputs here?

    Thanks in advanced.

    All I want to get is the value of the 1st field from the database to assign as the Id of my tag on the 2nd column.

    I appreciate your inputs.

    Thank you very much.

    Your fnRender approach looks fine, but you might want to consider using bUseRendered to stop DataTables from overwriting your data.

    Thank you very much Allan for your inputs,

    I am going to use this bUseRendered before my another fnRender.

    I appreciate that much.

    Best regards
