Javascript – Selecting all text in HTML text input when clicked

htmljavascripttextinput

I have the following code to display a textbox in a HTML webpage.

<input type="text" id="userid" name="userid" value="Please enter the user ID" />

When the page displays, the text contains the Please enter the user ID message. However, I found that the user needs to click 3 times in order to select all the text (in this case it is Please enter the user ID).

Is it possible to select the entire text with only one click?

Edit:

Sorry, I forgot to say: I must use the input type="text"

Best Solution

You can use this javascript snippet:

<input onClick="this.select();" value="Sample Text" />

But apparently it doesn't work on mobile Safari. In those cases you can use:

<input onClick="this.setSelectionRange(0, this.value.length)" value="Sample Text" />
