我想在名为“.reqF”的类未填充时显示警告弹出窗口，并在填充所有“.reqF”时将表单发送到操作页面..
这是我的表格

function updateTotal()

console.log('error');

} else empty = true;

if (empty == true)

var hiddenTot = jQuery('.reqFamount').val() ;
//alert (hiddenTot);
jQuery(".totalAmount").val(hiddenTot);
});
});
</script>
但问题是，仅当最后一个元素/成绩未填写时，它才会显示 #myModalforErrorMsg 框。
只有在填写年级后，并且当我将其他.reqF字段留空时，我才能提交表单..
这是为什么？
有时它可以在本地主机上运行，但不能在 WordPress 中运行..
我缺少什么？
最佳答案
此代码片段有问题
jQuery('.reqF').each(function() {
if (jQuery(this).val() === '') {
console.log('error');
empty = false;
} else empty = true;
});
if (empty == true)
jQuery('#myModal').modal('toggle');
else
//console.log('your error message');
jQuery('#myModalforErrorMsg').modal('toggle');
因为，您正在迭代所有元素，如果最后一个元素填充为空，则变为 true，因此不会显示错误。你想要的是，如果任何一个空是假的，你就会显示错误。 您可以如下修改 if 循环以使其工作。将空初始化为 true。
if (jQuery(this).val() === '') {
console.log('error');
empty = empty && false;
} else empty = empty && true;
关于javascript - .each jQuery 仅以这种形式捕获最后一个元素，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42910653/
