我有以下代碼,它在限制字符和顯示警報時適用於我,但我試圖限制字而不是字符。任何人都可以幫忙嗎?謝謝!帶警報的文本區域限制字
<script type="text/javascript">
$(function() {
$('a[href^="#"]').click(function (e) {
if ($("#promotion_image_description").val().length < 1) {
alert("You must enter your story!");
return false;
}
if ($("#promotion_image_description").val().length > 1300) {
alert("Your story can not be longer than 250 words!");
return false;
} else {
switch ($(this).attr('href')) {
case '#promotion':
$('#promotion_facebook_id_block, #promotion_name_block, #promotion_email_block, #promotion_address_1_block, #promotion_csz_block, #promotion_country_block, #promotion_phone_block, #promotion_custom_field_9_block, #promotion_custom_field_8_block, #promotion_custom_field_4_block, #promotion_custom_field_2_block, #promotion_custom_field_5_block, #promotion_custom_field_6_block, #promotion_custom_field_3_block, #promotion_agree_block, #promotion_submit_block, #disclaimer_promotion').show();
$('#promotion_custom_field_10_block, #promotion_image_description_block, #promotion_custom_field_11_block').hide();
e.preventDefault();
break;
}
}
});
});
</script>
