Meteor show update field instead of item if update clicked -

-

i have simplest meteor project ever, i'm stuck @ basic. have 1 form field, , when enter item goes mongo collection. retrieve , display collection, along buttons delete or edit. want happen click edit, , item becomes text box (prepopulated original value) can change, hit return, , have item updated. i'm stuck @ how pass _id along and/or how convert correct entry field.

my .html file:

<head>   <title>memorial</title> </head>  <body>   <h1>memorial testing!</h1>  <form class="new-task">     <input type="text" name="text" placehoder="type stuff here" /> </form>     {{> listing}} </body>   <template name="listing">     <ul>         {{#each tasks}}             {{> crudlist}}         {{/each}}     </ul> </template>  <template name="crudlist">     {{#if editor}}         {{#if editid == this._id}}             <li><input type="text" name="text" placehoder="type stuff here" value="{{text}}"/></li>         {{else}}             <li>{{text}} :: <button name="delete" class="delete">delete</button><button name="edit" class="edit">edit</button></li>         {{/if}}     {{/if}} </template>

my .js file:

tasks = new mongo.collection("tasks");  if (meteor.isclient) {    template.listing.helpers({     tasks: function() {       return tasks.find({});     }   });    template.crudlist.helpers({     editor: function() {       return session.get("editor");     },     editid: function() {       return session.get("editid");     }   });     template.body.events({     "submit .new-task": function (event) {       var text = event.target.text.value;        tasks.insert({         text: text,         createdat: new date()       });       event.target.text.value = "";       return false;     }   });     template.crudlist.events({     "click .delete": function () {       tasks.remove(this._id);     },     "click .edit": function () {       session.set("editor","true");       session.set("editid",this._id);     }   }); }   if (meteor.isserver) {   meteor.startup(function () {     // code run on server @ startup   }); }

thanks help.

to you've clicked on should use event.target documentation http://docs.meteor.com/#/full/eventmaps.

template.crudlist.events({     "click .delete": function (event,template) {       var whatyoujustclicked = event.target,           targetid = $(whatyoujustclicked).attr('id')     },     "click .edit": function (event,template) {       var whatyoujustclicked = event.target,           targetid = $(whatyoujustclicked).attr('id')       session.set("editor","true");       session.set("editid",targetid);     }

});
