How do I remove the first character from a link's text with jQuery?

I want to remove first character from link's text with jQuery.

<span class="test1"> +123.23 </span>
<span class="test2"> -13.23 </span>

I want to remove the "+" and "-" from with jQuery.

Output:

<span class="test1"> 123.23 </span>
<span class="test2开发者_如何学Python"> 13.23 </span>

var val = $("span").html();
$("span").html(val.substring(1, val.length));

$("span.test1, span.test2").each(function() {
  $(this).text($(this).text().replace(/[+-]/, ""));
});

// get the current text
text1 = $(".test1").html();
// set the text to the substring starting at the third character
$(".test1").html(text1.substring(2)); // extract to the end of the string

text2 = $(".test2").html();
$(".test2").html(" " + text2.substring(2)); // looks like you want to keep the leading space

you can get/set the HTML using .html() and remove the first character using .substring(), I think it's pretty clear now, you just need to write a 2 (or 3) lines code.
