Recently, I encountered a predicament with a dropdownlist populated from a datasource. Following a certain event, my goal is to eliminate a single item from the dropdownlist identified by id = 22. Although I recognize this may not be the best practice due to hardcoding, time constraints are pressing for someone like myself who is relatively new to coding. Is it achievable? If so, what steps should I take to accomplish this task?
This method provides a straightforward solution using the Kendo DataSource remove function for achieving the task at hand. It assumes that your dropdown menu is linked to an object with an "id" property. In case you are working with the typical text/value pair object, simply replace the if statement with if (item.Value == 22).
var dropdown = $('#dropDownId').data("kendoDropDownList");
var raw = dropdown.dataSource.data();
var length = raw.length;
var item, i;
for(i=length-1; i>=0; i--){
item = raw[i];
if (item.id == 22) {
dataSource.remove(item);
break;
}
}
Source:
To remove this specific item as a child of its parent, you can first access the parent element:
document.getElementById("22").parentNode.removeChild(document.getElementById("22"));
The getElementById("22") function retrieves an element with the id "22"
When we refer to parentNode, we are talking about the parent element. In this case, it is the dropdown.
Using
