您好我有一个表单我想验证字段，我现在正在使用float sx=0.5f; // slow down translation factor in x axis by half
float sy=0.5f; // slow down translation factor in y axis by half
model.getSprite().translate(x*sx, y*sy);
第一个字段jquery验证工作正常它禁用按钮直到电话字段为空。在第二个字段之后，数字条件很好，但问题是它不是检查第一个字段是否为空。意味着条件变为真，而不检查第一个字段是否为空。希望我能够全面了解我的问题
jQuery代码
name我的表单
jQuery(document).ready(function($) {
setTimeout(function(){
$('#sfp_Modal').modal('show');
