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.
您可以使用 .html() 获取/设置 HTML 并使用 .substring() 删除第一个字符，我认为现在很清楚，您只需要编写 2（或 3）行代码。
