Using Javascript to determine if a DropDown list is currently disabled

This code snippet checks whether the DropDownList is disabled or not.

function CheckRowBeforeSaving() {
  for (i = 0; i < document.forms[0].length; i++) {
      if (e.id.indexOf("_ddlTask") != -1) {
         var disabled = e.disabled;
          alert(disabled);
    }
  }
}

Upon testing, it was observed that when the DropDownList is enabled, the alert message displays "False". However, when the DropDownList is disabled, the alert doesn't show up at all. Any ideas on how to resolve this issue?

EDIT

Although I have removed the condition, the outcome remains unchanged.

Your assistance is greatly appreciated.

Answer №1

Upon observation, I have noticed that the alert box displays the message "False" when the DropDownList is enabled. However, when the DropDownList is disabled, the alert message does not appear at all. How can this issue be resolved?

To address this problem, simply eliminate the condition that specifically checks for disabled==false since it is already set to disabled (disabled=true)

if (disabled == false) { // <-----REMOVE THIS LINE
       alert(disabled);
}

Answer №2

Substitute

if (enabled == true) {
            console.log(enabled);
         }

Simply use console.log(enabled);

This means eliminating the validation for enabled

Answer №3

Check out this helpful link for information on ASP.NET client IDs.

Here is a useful JavaScript function that can be used to check rows before saving:

function ValidateRowBeforeSaving() {
    for (var j = 0; j < document.forms[0].length; j++) {
        if (element.id.indexOf('<%= myElement.ClientID %>') != -1) {
            var isDisabled = element.disabled;
            alert("Element disabled: " + isDisabled);
        }
    }
}
