Using JavaScript Image Map

JavaScript can be used to create client-side image maps, which are defined using the <map> and <area> tags in conjunction with the usemap attribute of the <img /> tag.

The <map> element acts as a container for defining clickable hotspots within an image. Each <area> tag specifies a shape and coordinates for the hotspot.

Below is an example demonstrating how to use an image map with JavaScript to display different messages when hovering over specific areas of an image: 

<html>
<head>
<title>Using JavaScript Image Map</title>
<script type="text/javascript">
function showTutorial(name) {
  document.myform.stage.value = name;
}
</script>
</head>
<body>
<form name="myform">
  <input type="text" name="stage" size="20" />
</form>

<img src="/images/usemap.gif" alt="HTML Map" 
     border="0" usemap="#tutorials"/>

<map name="tutorials">
  <area shape="poly" coords="74,0,113,29,98,72,52,72,38,27"
        href="/perl/index.htm" alt="Perl Tutorial"
        target="_self" 
        onMouseOver="showTutorial('perl')" 
        onMouseOut="showTutorial('')"/>

  <area shape="rect" coords="22,83,126,125"
        href="/html/index.htm" alt="HTML Tutorial" 
        target="_self" 
        onMouseOver="showTutorial('html')" 
        onMouseOut="showTutorial('')"/>

  <area shape="circle" coords="73,168,32"
        href="/php/index.htm" alt="PHP Tutorial"
        target="_self" 
        onMouseOver="showTutorial('php')" 
        onMouseOut="showTutorial('')"/>
</map>
</body>
</html>

Handling Change Events in jqGrid

Handling Change Events in jqGrid In this tutorial, we'll explore how to handle the change event in jqGrid to dynamically update another column based on the selected value. This approach is useful when you need to update related data based on user selections. Example Scenario Let's say we have a jqGrid table with two columns: Country and State. When the user selects a country, the State column should dynamically update to show the relevant states for the selected country. Implementation We'll use the dataEvents option in the colModel configuration to handle the change event. HTML Structure First, let's set up our basic HTML structure: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>H...

Persisting jqGrid State with Cookies

Persisting jqGrid State with Cookies jqGrid is an excellent jQuery plugin for displaying a grid. To enhance user experience, we added some filter possibilities and used jQuery to update the URL where data was fetched from. However, when users navigated away from the grid and returned, it would reset to its start position, losing any filtering or sorting they had set. To solve this, we needed to store the user's selections. Here are two JavaScript functions that achieve this using cookies: function saveGridToCookie(name, grid) { var gridInfo = new Object(); name = name + window.location.pathname; gridInfo.url = grid.jqGrid('getGridParam', 'url'); gridInfo.sortname = grid.jqGrid('getGridParam', 'sortname'); gridInfo.sortorder = grid.jqGrid('getGridParam', 'sortorder'); gridInfo.selrow = grid.jqGrid('getGridParam', 'selro...
