Question

大家好我尝试从颜色词$("#Tcounter").css("color","black")输入一个颜色代码编号;在此脚本中，从"black"到"#317D29"。我怎样才能做到这一点？

<script type="text/javascript">
$(document).ready(function()  {
    var Tcharacters = <?php echo $max_character_length_title; ?>;
    $("#Tcounter").append("<small><?php osc_esc_js(_e('You have','ctg_housing')); ?> <strong>"+  Tcharacters+"</strong> <?php osc_esc_js(_e('characters remaining','ctg_housing')); ?></small>");
    $("#title<?php echo osc_current_user_locale(); ?>").keyup(function(){
    if($(this).val().length > Tcharacters){
        $(this).val($(this).val().substr(0, Tcharacters));
        }
    var Tremaining = Tcharacters -  $(this).val().length;
    $("#Tcounter").html("<small><?php osc_esc_js(_e('You have','ctg_housing')); ?> <strong>"+  Tremaining+"</strong> <?php osc_esc_js(_e('characters remaining','ctg_housing')); ?></small>");
    if(Tremaining <= 10)
    {
        $("#Tcounter").css("color","red");
    }
    else
    {
        $("#Tcounter").css("color","black");
    }
});
</script>

首先让我知道Tcounter是id或class。

如果Tcounter是课堂使用：$(".Tcounter").css("color","#ff0000");

如果Tcounter是id，则使用：$("#Tcounter").css("color","#ff0000");

                $(".Tcounter").css("color","#ff0000");
     			$("#Tcounter").css("color","#ADFF2F");
    });
});

<body>
<p class="Tcounter">Red Color using class</p>
<p id="Tcounter" >Green Color using Id</p>
<button >Set background-color of p</button>
