Hyperlink to Call JavaScript Function

You can show hyperlink using set_col_link for static link or set_col_dynalink for dynamic link. What about if you want to do something even fancier, like open a new window, or trigger a JavaScript event when hyperlink is clicked?

To call JavaScript function on hyperlink click, use “showlink” in set_col_format method.

In the following example, the first set_col_format displays text in alert window using JavaScript function “myFunction” to retrieved text from a different cell in the same row. The second does a phpgrid.com site search using jQuery Ajax function “phpGridSiteAjaxSearch”, and displays the result in a alert message window.

$dg = new C_DataGrid("select * from products", "productCode", "products");
$dg -> set_col_title("productCode", "Product Code");
$dg -> set_col_title("productName", "Product Name");
$dg -> set_col_title("productLine", "Product Line");

$dg->set_col_format("productLine", "showlink", array("baseLinkUrl"=>"javascript:", "target"=>"_self",
    "showAction"=>"myFunction(jQuery('#products'),'",
    "addParam"=>"');"));                                                                                                                          

$dg->set_col_format("productName", "showlink", array("baseLinkUrl"=>"javascript:", "target"=>"_self",
    "showAction"=>"phpGridSiteAjaxSearch(jQuery('#products'),'",
    "addParam"=>"');"));                                                                                                                          
$dg -> display();
