How to have two buttons in JQuery Steps

问题:

I really need some help here. So I am using one Jquery Steps PlugIn. Now in this PlugIn when we go to the last tab it has a button name as "Finish" when clicked calls "onFinishing" Method.

onFinishing: function () {
            var loadedPrefix = MyNamespace.loadedPrefix;
            var inputBoxPrefix = $('#SitePrefix').val();
            $.ajax({
                type: 'POST',
                url: '/Settings/IsPrefixExists',
                data: { newPrefix: inputBoxPrefix, prefixLoadedFromDB: loadedPrefix },
                success: function (data) {
                      // do some stuff here
                    }
                },
                error: function () {
                    DisplayError('Failed to load the data.');
                }
            }); 
        }

Now above works perfectly fine. But my manager wants me to have two button there. One as "Save" and another as "Submit". And clicking on each of them will perform a different action. But this plugin has only one "Finish" button. And it is getting generated via PlugIn's Javascript code. Can I somehow use JQuery/Javascript to have one more button there, and write some code against it.

Using the onStepChanged event found in the Steps plugin documentation...

You could do this:

$( window ).load(function() {
  $("#example-basic").steps({
    headerTag: "h3",
    bodyTag: "section",
    transitionEffect: "slideLeft",
    autoFocus: true,
    onFinishing: function () {
      alert("Hello");
    },
    onStepChanged:function (event, currentIndex, newIndex) {
      console.log("Step changed to: " + currentIndex);

      if(currentIndex == 2){
        console.log("ok");
        var saveA = $("<a>").attr("href","#").addClass("saveBtn").text("Save");
        var saveBtn = $("<li>").attr("aria-disabled",false).append(saveA);

        $(document).find(".actions ul").prepend(saveBtn)
      }else{
        $(".actions").find(".saveBtn").remove();
      }
      return true;
    },

  });


  // on Save button click
  $(".actions").on("click",".saveBtn",function(){
    alert("Saving!");
  });
});

Regardless of using the steps plugin, you can add a save button on the last step and bind a click handler like you would with any normal button:

<input id='btnSave' name='btnSave' value='Save' type='button'>

and in your javascript:

$('#btnSave').click(function() {
    $.ajax({
            type: 'POST',
            url: '/Settings/SavePrefix',
            data: { newPrefix: inputBoxPrefix, prefixLoadedFromDB: loadedPrefix },
            success: function (data) {
                  // do some stuff here
                }
            },
            error: function () {
                DisplayError('Failed to save the data.');
            }
        }); 
});

You can also inject the button as needed.

Using the default plugin inside of a tag with and id of #steps-uid-8 you can get the finish element with $('#steps-uid-8 a').last(); It is nested inside of a <li> which is inside of a <ul> so you can get a reference to the ul $('#steps-uid-8 a').last(),parent().parent()

Using that reference you can add a hyperlink so your "button" has the same style as the plugin, like this:

$('#steps-uid-8 a').last().parent().parent().prepend("<li><a id='btnSave' name='btnSave'>Save</a></li>");

You can also add a function in your settings to only show the Save button on the last step if you need to

var numberOfSteps=3,// change as needed

var settings = {
    onStepChanged: function (event, currentIndex, priorIndex) 
    { 
    if(currentIndex==numberOfSteps) $('#btnSave').show();
    else $('#btnSave').hide();
    }
}

Using your fiddle, the onload Javascript was simply changed.

<script>
      function saveMe() {
        alert('Saving');
      }
      $(window).load(function() {
        var lastStep = 2;
        $("#example-basic").steps({
          headerTag: "h3",
          bodyTag: "section",
          transitionEffect: "slideLeft",
          onStepChanged: function(event, currentIndex, priorIndex) {
            //console.log(currentIndex);
            if (currentIndex == lastStep) $('#btnSave').show();
            else $('#btnSave').hide();
          },
          autoFocus: true,
          onFinishing: function() {
            alert("Hello");
          },
        }).find('a')
        .last().parent().parent()
        .prepend("<li><a style='display:none' href='#save' id='btnSave' name='btnSave' onclick='saveMe()'>Save</a></li>");
      });
    </script>
