我需要用 javascript 在字段中放置一个掩码。例如：+55 (11) 98888-0000 或 +55 (11) 8888-0000。

我有一个像 (11) 99999-9999 或 (11) 9999-9999 一样工作的 javascript 函数，我需要修改它以离开上面的示例。这是功能代码。

function mascara(o,f){

    v_fun=f
    setTimeout("execmascara()",1)
}
function execmascara(){
    v_obj.value=v_fun(v_obj.value)
}
function mtel(v){
    v=v.replace(/\D/g,"");                  // Removes all non-digit
    v=v.replace(/^(\d{2})(\d)/g,"($1) $2"); // Place parentheses around the first two digits
    v=v.replace(/(\d)(\d{4})$/,"$1-$2");    // Places hyphen between the fourth and fifth digits
    return v;
}
function id( el ){
	return document.getElementById( el );
}
window.onload = function(){
	id('telefone').onkeyup = function(){
		mascara( this, mtel );
	}
}

您可以根据函数输入文本的长度指定条件

对于 +55 (11) 8888-0000 这个使用下面 exp v=v.replace(/^(\d{2})(\d{2})(\d{4})(\d)/g," +"+"$1 ($2) $3-$4"); 和最大长度= 18

对于 +55 (11) 98888-0000 使用下面的 exp v=v.replace(/^(\d{2})(\d{2})(\d{5})(\d)/g,"+ "+"$1 ($2) $3-$4");并且最大长度=19
