我遇到了Fuel UX向导的问题。 当我按下燃料ux向导上的下一个按钮时,我发送使用validate_step选择的category_id(步骤)和来自php的json对象的响应。
这第一步工作正常,但是当我尝试读取validate_step(step)函数的结果时,我在控制台上出现错误。
问题在于:
vrspx = validate_step(step);
console.log('Validation(' + step + ')= ' + vrspx); // CONSOLE : Validation(1)= undefined
if(vrspx === 'ok'){ ....
vrspx变量返回未完成。
我使用的是燃料ux,我对jquery有中级经验,我不知道这是一个很好的方法,或者如何开始在向导的每一步进行ajax验证。
希望有人可以帮助我。提前致谢!

您所看到的问题是因为必须立即(同步)进行验证决策,并且在AJAX请求完成之前不能推迟。一种策略是始终使验证失败,然后处理从验证的ajax回调中移动向导步骤。这是一个开始:
$('#MyWizard').on('stepclick change', function (e, data) {
console.log('step ' + data.step + ' requested');
// Cancel the click to allow
// validate_step to process
e.preventDefault();
// Perform AJAX validation. The AJAX
// callback can call $('#MyWizard').wizard('next')
// or otherwise modify the wizard as appropriate
validate_step(data.step);
});
