我在SmartWizard中有以下代码部分。我想为每个HTML控件添加自定义验证。在SmartWizard中添加自定义验证

<form id="myform"> 
    <input type="text" name="field1" /> 
    <br/> 
    <input type="text" name="field2" /> 
    <br/> 
    <input type="submit" /> 
</form> 

我试过下面的代码,但不工作。

function leaveAStepCallback(obj){ 
       var step_num= obj.attr('rel'); // get the current step number 
     return validateSteps(step_num); // return false to stay on step and true to continue navigation 
     }

我知道这是非常过时的,但我要去反正回答,因为我发现这个职位做自己

//..init wizard 
onLeaveStep: function(obj, context){ 
    //Validate the current step         
    var frst = "#step-"+context.fromStep; 
    var container = this.elmStepContainer.find(frst); 
    //container now contains everything in the box 
    //you can now container.find("...") to get fields 
    //and then run some regex or whatever you want to do the validation 
    if(invalid_fields.length > 0){ 
     return false ; 
    }else{ return true;}}, 
//...the rest of the wizard init

之前,这将有助于为他人寻找同样的问题,这实现来自插件的第4版。对这个事件方法返回false将会停止这些步骤的传播,因此保持同一步错误。

$("#smartwizard").on("leaveStep", function(e, anchorObject, stepNumber) { 
    var formElms = $(anchorObject.attr('href')).find("input, textarea"); 
    var hasError = false; 
    $.each(formElms, function(i, elm){ 
     if(elm.val().length == 0){ 
      hasError = true; 
     } 
    }); 
    return !hasError; 
});
