My app was working fine till IE9, now it stopped working when I upgraded it to IE11. Here is a sample html and js .
ISSUE
In the first run ie. on load it works well. But when I select PDA brand, second dropdown's all options went blank.
In console there was a script error Invalid Calling Object error on object clonedOptions.
function dynamicSelect(id1, id2) {
//alert("Everytime")
// Browser and feature tests to see if there is enough W3C DOM support
// Obtain references to both select boxes
var sel1 = document.getElementById(id1);
var sel2 = document.getElementById(id2);
// Clone the dynamic select box
var clone = sel2.cloneNode(true);
// Obtain references to all cloned options
var clonedOptions = clone.getElementsByTagName("option");
// Onload init: call a generic function to display the related options in the dynamic select box
refreshDynamicSelectOptions(sel1, sel2, clonedOptions);
// Onchange of the main select box: call a generic function to display the related options in the dynamic select box
sel1.onchange = function() {
refreshDynamicSelectOptions(sel1, sel2, clonedOptions);
};
}
function refreshDynamicSelectOptions(sel1, sel2, clonedOptions) {
while (sel2.options.length) {
sel2.remove(0);
}
//alert(sel1.options[sel1.selectedIndex].value)
// Create regular expression objects for "select" and the value of the selected option of the main select box as class names
var pattern1 = /( |^)(select)( |$)/;
var pattern2 = new RegExp("( |^)(" + sel1.options[sel1.selectedIndex].value + ")( |$)");
// Iterate through all cloned options
//alert(clonedOptions.length);
for (var i = 0; i < clonedOptions.length; i++) {
// If the classname of a cloned option either equals "select" or equals the value of the selected option of the main select box
if (clonedOptions[i].className.match(pattern1) || clonedOptions[i].className.match(pattern2)) {
// Clone the option from the hidden option pool and append it to the dynamic select box
//alert("Did match")
sel2.appendChild(clonedOptions[i].cloneNode(true));
//alert(sel2.options[1]);
}
}
