在页面加载时触发更改事件它不会在页面加载时触发

Question

我有以下js代码：

<script type="text/javascript">

    jQuery(document).ready(function($){

        // List of contributors quantities inputs
        var honorCont   = $('.honor-contributor input[type="number"]');
        var premCont    = $('.premium-contributor input[type="number"]');
        var plusCont    = $('.plus-contributor input[type="number"]');
        var adultCont   = $('.adult-contributor input[type="number"]');
        var kidCont     = $('.kid-contributor input[type="number"]');
        var honorContPrevNum,  premContPrevNum, plusContPrevNum, adultContPrevNum, kidContPrevNum;
        honorContPrevNum = premContPrevNum = plusContPrevNum = adultContPrevNum = kidContPrevNum = 0;


        // Hide the titles on DOM load
        $('.honor-cont, .t-size, .prem-cont, .plus-cont, .adult-cont, .kid-cont').addClass('hide');

        /* Honor contributor */
        $(honorCont).change(function (){
            var honorContUpdatedNum = honorCont.val();
            if( honorContUpdatedNum > honorContPrevNum && honorContUpdatedNum > 1 ) {
                gfRepeater_repeatRepeater(4, 1);
            } else {
                gfRepeater_unrepeatRepeater(4, 1);
            }
            if( honorContUpdatedNum > 0 ){
                $('.honor-cont').removeClass('hide');
            }
            else{
                $('.honor-cont').addClass('hide');
            }
            honorContPrevNum = honorContUpdatedNum;

        });

        /* Premium contributor */
        $(premCont).change(function (){
            var premContUpdatedNum = premCont.val();
            if( premContUpdatedNum > premContPrevNum && premContUpdatedNum > 1 ) {
                gfRepeater_repeatRepeater(4, 2);
            } else {
                gfRepeater_unrepeatRepeater(4, 2);
            }
            if( premContUpdatedNum > 0 ){
                $('.prem-cont').removeClass('hide');
            }
            else{
                $('.prem-cont').addClass('hide');
            }
            premContPrevNum = premContUpdatedNum;
        });

        /* Plus contributor */
        $(plusCont).change(function () {
            var plusContUpdatedNum = plusCont.val();
            if( plusContUpdatedNum > plusContPrevNum && plusContUpdatedNum > 1 ){
                gfRepeater_repeatRepeater(4, 3);
            } else {
                gfRepeater_unrepeatRepeater(4, 3);
            }
            if( plusContUpdatedNum > 0 ){
                $('.plus-cont').removeClass('hide');
            }
            else{
                $('.plus-cont').addClass('hide');
            }
            plusContPrevNum = plusContUpdatedNum;

        });

        /* Adult contributor */
        $(adultCont).change(function () {
            var adultContUpdatedNum = adultCont.val();
            if( adultContUpdatedNum > adultContPrevNum && adultContUpdatedNum > 1 ) {
                gfRepeater_repeatRepeater(4, 4);
            } else {
                gfRepeater_unrepeatRepeater(4, 4);
            }
            if( adultContUpdatedNum > 0 ){
                $('.adult-cont').removeClass('hide');
            }
            else{
                $('.adult-cont').addClass('hide');
            }
            adultContPrevNum = adultContUpdatedNum;

        });

        /* Kid contributor */
        $(kidCont).change(function () {
            var kidContUpdatedNum = kidCont.val();
            if( kidContUpdatedNum > kidContPrevNum && kidContUpdatedNum > 1 ) {
                gfRepeater_repeatRepeater(4, 5);
            } else {
                gfRepeater_unrepeatRepeater(4, 5);
            }
            if( kidContUpdatedNum > 0 ){
                $('.kid-cont').removeClass('hide');
            }
            else{
                $('.kid-cont').addClass('hide');
            }
            kidContPrevNum = kidContUpdatedNum;

        });


    });
</script>

但是当页面加载时，我收到此错误：

当我调试这个时，我看到第一个更改事件是页面加载时触发，当它只在输入类型改变后才会触发，我想这与错误有关。知道为什么会这样吗？

提前致谢！

我想问题出在你的功能中。您正在传递参数，您应该用逗号括起来：gfRepeater_repeatRepeater("<?php echo $als_campaign_form_id; ?>", 1);

尝试在所有功能中加入逗号，然后检查。感谢
