jqgrid checkbox change event

I have true/false values in my database. I want to update them with checkbox in jqgrid. Once the value is set to true, it will remain true and should not change. Please take a look at my column model :

{
    name : 'available',
    width : 12,
    resizable: true,
    editable: true,
    align: 'center',
    edittype:'checkbox',
    formatter: "checkbox", formatoptions: {disabled : false},
    classes:'check',
    editrules:{required:false}, editoptions:{size:39,value:"True:False"}
}

I'm trying to capture the event when checkbox is checked, currently they are all unchecked, so far I've tried:

jq(".check input").each(function(){
    jq(this).click(function(){
        aler("works");
    });
});

jq("input[type='checkbox']").change(function(){
    alert("works");
}); 

jq(":checkbox").parent().click(function(evt) {
    if (evt.target.type !== 'checkbox') {
        var $checkbox = jq(":checkbox", this);
        $checkbox.attr('checked', !$checkbox.attr('checked'));
        $checkbox.change();
        alert("");
    }
});

None of these work, I'm stuck don't know what else to try.

When inspect checkbox code with firebug it looks like this :

<input type="checkbox" offval="no" val开发者_JS百科ue="false">


You can create a custom formatter. In your grid,

formatter: cboxFormatter,

Then define the function,

function cboxFormatter(cellvalue, options, rowObject)
{
  return '<input type="checkbox"' + (cellvalue ? ' checked="checked"' : '') + 
      'onclick="alert(' + options.rowId + ')"/>';
}

You can use onclick to perform your task or call a function.


The usage of the custom formatter is one of the possibilities. One can also use unobtrusive style of onclick binding

First one defines

var grid = $("#list"),
    getColumnIndexByName = function(columnName) {
        var cm = grid.jqGrid('getGridParam','colModel'),i=0,l=cm.length;
        for (; i<l; i++) {
            if (cm[i].name===columnName) {
                return i; // return the index
            }
        }
        return -1;
    },
    disableIfChecked = function(elem){
        if ($(elem).is(':checked')) {
            $(elem).attr('disabled',true);
        }
    };

Then one can use the in the loadComplete the code like

loadComplete: function() {
    var i=getColumnIndexByName('closed');
    // nth-child need 1-based index so we use (i+1) below
    $("tbody > tr.jqgrow > td:nth-child("+(i+1)+") > input",
      this).click(function(e) {
        disableIfChecked(this);
    }).each(function(e) {
        disableIfChecked(this);
    });
}

See the corresponding demo here.


This worked for me:

    // Listen for Click Events on the 'Process' check box column
    $(document).on("click", "td[aria-describedby='grdOrders_Process']", function (e) {
        var checked = $(e.target).is(":checked")

        var rowId = $(e.target).closest("tr").attr("id")
        rowData = jQuery("#grdOrders").getRowData(rowId);

        alert("Checked: " + checked)
        alert("OrderNo: " + rowData.OrderNo);
        alert("Name: " + rowData.Name);
    });
