I have a aspxcombobox with ID="comboSubjectCategory", can I get the selected value/text using javascript function? 我有一个ID =“ comboSubjectCategory”的aspxcombobox,我可以使用javascript函数获取选定的值/文本吗? thanks lot...I tried this but it does not works.
非常感谢...我尝试了这个,但是没有用。
function getValue() {
var combo = document.getElementById('comboSubjectCategory').value;
alert(combo);
}
The ASPxComboBox is not a simple HTML element. ASPxComboBox不是简单的HTML元素。 In the browser, it is represented by the ASPxClientComboBox Class .
在浏览器中,它由ASPxClientComboBox类表示。 Use its GetValue , GetText or GetSelectedItem methods to obtain the selected value.
使用其GetValue , GetText或GetSelectedItem方法获取选定的值。
You can obtain the ASPxClientComboBox instance by the name assigned to the ClientInstanceName property of the ASPxComboBox control. 您可以通过分配给ASPxComboBox控件的ClientInstanceName属性的名称来获取ASPxClientComboBox实例。
