Knockout

Knockout Click Binding:

<td>
<a data-bind="text:title,click:$parent.openRecord"/>
</td>

if you use href in "a" tag, the function wont be called.

Inside your view model,

var self = this;
self.openRecord = function (record) { // Write your code here for click operation };


Knockout Dirty flag:


Create new ko object :
ko.dirtyFlag = function (root, isInitiallyDirty) { var result = function () { }, _initialState = ko.observable(ko.toJSON(root)), _isInitiallyDirty = ko.observable(isInitiallyDirty); result.isDirty = ko.computed(function () { return _isInitiallyDirty() || _initialState() !== ko.toJSON(root); }); result.reset = function () { _initialState(ko.toJSON(root)); _isInitiallyDirty(false); }; return result; };


In your view model, you can use the flag like this:
var isDirty = false; //set to true to load your item as Dirty.
  self.dirtyFlag = new ko.dirtyFlag(this, isDirty);

To check for a specific item in your Model as dirty or not,
        self.quantitydirtyFlag = new ko.dirtyFlag(self.quantity, isDirty);

        self.dirtyItems = ko.computed(function () {
        self.isDirty = ko.computed(function () {

            return ko.utils.arrayFilter(self.items(), function (item) {

                return item.dirtyFlag.isDirty();

            });

        }, self);

            return self.dirtyItems().length > 0;

        }, self);

you can check for whether the item is dirty or not by,

record.dirtyFlag.isDirty()
for the specific item,
record.quantitydirtyFlag.isDirty()

Dirty flag original reference here.

Parse Json Date to Date Object

Parse jsondate in JavaScript to a Date Object:
Below are two methods I use  
Method 1:
var jsonDate = "/Date(1224043200000)/"
var value = new Date(parseInt(jsonDate.substr(6)));


Method 2:
var jsonDate = "/Date(1224043200000)/"
var value = new Date(parseInt(jsonDate.replace(/(^.*\()|([+-].*$)/g, '')));

if you want in "mm/dd/yyyy" format, use this along with the above script
var dat = value.getMonth()+ 1 + "/" + value.getDate()+ "/" +value.getFullYear();

Ajax request from HTML to CRM2011/ CRM2013

var requestmain = fetchxml;

 $.ajax(
            {
                type: "POST",
                contentType: "application/json; charset=utf-8",
                datatype: "json",
                url: serverurl + "/XRMServices/2011/Organization.svc/web",
                async: false,
                data: requestMain,
                headers: { "Accept": "application/xml, text/xml, */*", "Content-Type": "text/xml; charset=utf-8", "SOAPAction": "http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/RetrieveMultiple" }

            })
            .done(function (XMLHttpRequest) {
                var strResponse = GetXmlValue(XMLHttpRequest.childNodes[0]);
                xmlDoc = $.parseXML(strResponse);
            })
            .fail(function (XMLHttpRequest) {
                alert("Error retrieving accounts using fetch xml");
            })
            .always(function (XMLHttpRequest) {
            });

function GetXmlValue(value) {
    if (value.xml == undefined) {
        return (new XMLSerializer()).serializeToString(value);
    }
    return value.xml;
}
 

open link url inside a div/iframe

<html>
<head>
<script type="text/javascript">

function  showPage (which) {
    document.getElementById('xrmforms').innerHTML = '<' + 'iframe id="crmpage" src="' + which + '"width="100%" height="600px;" scrolling="auto"></iframe>';

}

</script>

</head>
<body>
<a href="http://www.google.com" onclick="showPage(this.href);return false;">Click here</a>


<div id="xforms">
</div>

</body>
</html>

Replace certain character JavaScript

To replace certain characters in javascript:

In this example, i'm replacing '&' with '&amp;' in the entire string.


function formatTexts(linkText) {
    var patt1 = /&/g;
    var patt1replStr = "&amp;";

    var matchPatt = linkText.match(patt1);

    var pattformat = /&amp;/g;
    var matchformatted = "";
    if (matchPatt != null && matchPatt.length > 0) {
        while (matchformatted.length < matchPatt.length) {
            linkText = linkText.replace(linkText.match(patt1)[0], patt1replStr);
            matchformatted = linkText.match(pattformat);
        }
    }
    return linkText;
}

HtmlEncoding in Javascript

Often when executing fetchxml in javascript or when creating tables throught javascript, you would face the error because the values are not htmlencoded.


function htmlEncode(value) {
    return $('<div/>').text(value).html();
}
function htmlDecode(value) {
    return $('<div/>').html(value).text();
}


This encodes the default characters that have to be encoded.

Hide CrmNavBar and CrmRibbon through javascript

//This toggles ribbon visibility, but doesnt move the form area up
window.top.document.getElementById("minimizeribbon").fireEvent("onclick");


// Hide the Ribbon toolbar and move the form Content area to the top of the window.
window.top.document.getElementById("crmTopBar").style.display = "none";
window.top.document.getElementById("crmContentPanel").style.top = "0px"; //

//default values for showing ribbon and moving content area below ribbon

window.top.document.getElementById("crmTopBar").style.display = "";
window.top.document.getElementById("crmContentPanel").style.top = "135px"; //



// Hide Left Hand Nav bar / pane
document.getElementById("crmNavBar").parentElement.style.display = "none";
document.getElementById("tdAreas").parentElement.parentElement.parentElement.parentElement.colSpan = 2;



// Hide the Breadcrumb and Record Set Toolbar
document.getElementById("recordSetToolBar").parentElement.style.display = "none";

// Hide the Form Footer Bar
document.getElementById("crmFormFooter").parentElement.style.display = "none";

This will provide the record Guid as alert, reading the value from queryString.

Restrict Future date in CRM and restrict save event

To avoid future date in a date field in CRM Form and restrict save in such cases:

var today = new Date();

var filledDate = crmForm.all.new_testdate.DataValue;

if(filledDate > today)
{
   alert('filled in date is a future date. please enter appropriate date.');

 event.returnValue = false;
     return false;

}

To restrict save of crmfrom, we need to execute the following script onsave of the form.

 event.returnValue = false;

     return false; // if this line is not added, the rest of the script that follows this will get executed.
