Step 1: Kindly follow my intital post to understand how java script can be used in Content Editor Web Part.
Step 2: Consider a list like "Announcement" with custom "Yes\No" type column.
Step 3: Edit the page. You can modify the URL to edit NewForm.aspx. To the end of the URL append PageView=Shared&ToolPaneView=2. This will open the form in edit mode.
your URL must be like this http://sample.com/sites/BasicJs/Lists/Announcements/NewForm.aspx?PageView=Shared&ToolPaneView=2
Step 4: Add Content Editor Web Part.
Step 5: Write the following code in a text. save as html. upload into SharePoint.Link this html page to content editor web part or Write code in Web Part's text editor directly.
Step 6: Code
<html>
<head>
<SCRIPT type=text/javascript src="/mysites/myDocLibrary/JsFiles/jquery-1.4.2.min.js"></SCRIPT>
<SCRIPT type=text/javascript src="/mysites/myDocLibrary/JsFiles/JsFiles/jquery.SPServices-0.5.6.min.js"></SCRIPT>
<SCRIPT type=text/javascript>
$(document).ready(function()
{
var TopAnnouncementField = getTagFromIdentifierAndTitle("input","","Top Announcement");
//alert("Control is " + TopAnnouncementField.name);
EnableSelection(TopAnnouncementField);
});
function EnableSelection(TopAnnouncementField)
{
//alert("inside EnableSelection");
TopAnnouncementField.checked = "True";
}
function getTagFromIdentifierAndTitle(tagName, identifier, title)
{
var len = identifier.length;
var tags = document.getElementsByTagName(tagName);
for (var i=0; i < tags.length; i++)
{
var tempString = tags[i].id;
if (tags[i].title == title && (identifier == "" || tempString.indexOf(identifier) == tempString.length - len))
{ return tags[i]; }
}
return null;
}
</SCRIPT>
</head>
<Body></Body>
</html>
Step 7: To remove the identity that the code was generated from Content Editor Web Part, within the Web Part Setting, Under Appearance, For Chrome Type select "None". Click OK. Click Apply. Publish the Page. Now you can see that the column "Top Announcement" is checked.
Step 8: Check my next post to check this "Yes\No" column depending upon the value from the Query string.
