javascript - Change placeholder text based on the dropdown selection? -


I have a selection box with some options that the user chooses, when the user selects "first name" Then I want to place your first name in the placeholder text to be displayed next to the text box. Please find your piece of code below:

HTML: 

  & Lt; Id = "selection type" & gt; & Lt; Option value = "- 1" & gt; Choose one & lt; / Options & gt; & Lt; Option value = "0" & ​​gt; First name & lt; / Options & gt; & Lt; Option value = "1" & gt; Last name & lt; / Option & gt;   
  
 js:  
  var placeholder text = {"first name": "enter your first name", "last Name ":" Enter your last name "}; ("Change", function () {var selection = document.getElementById ("selectionType"); var input box = document.getElementById ("input box"); var selectedVal = $ ('# selectType') .find (': Selected '). Text (); if (placeholder text [selectedVal]! == undefined) {inputBox.placeholder = placeholderText [selectedVal];}});  
 
 It works fine in Chrome and FF, but it works in IE 8 & amp; 9 ... any help on this 
 
 View the demo:

Use it IE 8 & amp; Support in 9

Because IE 8 and 9 html5 do not support placeholders and only support in IE 10.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
