How do I move the cursor to the front of a textbox which has text in it?

开发者 https://www.devze.com 2023-03-20 14:38 出处:网络
I have this text box: <input type=\"text\" name=\"url\" id=\"url-input\" /> and this code: var input开发者_开发问答Text = \"Hello World\";

I have this text box:

<input type="text" name="url" id="url-input" />

and this code:

var input开发者_开发问答Text = "Hello World";
$(document).ready(function() {
  $("#url-input").focus();
  $("#url-input").val(inputText);
});

As it is, the cursor is displayed at the end of the textbox after the words "Hello World" (no matter in which order I add focus or change the value). How can I move it to the front?

Thanks

In decent web browsers, you have access to the selectionStart and selectionEnd properties which represent the selection. When they are both 0, it comes down to no selection and the caret at the beginning:

$("#url-input").prop('selectionStart', 0)
               .prop('selectionEnd', 0);

Another thing of jQuery is chaining: $(...).func1().func2(), so you need the selector once only.

Yet another thing of jQuery is that most functions support objects as parameter so you could also do:

$("#url-input").prop({ selectionStart: 0,
                       selectionEnd:   0 });


I use this small jquery plug in: https://gist.github.com/DrPheltRight/1007907
