spacebars

问题 This is somewhat of a part 2 to my last question. Thanks to some helpful folks, I now have a document that looks like this: { "_id" : "dndsZhRgbPK24n5LD", "createdAt" : ISODate("2014-11-26T16:28:02.655Z"), "data" : { "cat1" : 493.6, "cat2" : 740.4 }, "owner" : "GiWCb8jXbPfzyc5ZF", "text" : "asdf" } Specifically, I want to extract the value from each property of data in Spacebars and iterate over it to create a table - and I know the number of fields in object data but the number can vary. Yes

问题 I'm using meteor/spacebars and trying to format the output from an {{#each}}. I've found this question previously asked here but I've tried to apply the answers and for what ever reason they just clear the fields that were supposed to be formatted to give no output at all and I can't for the life of me figure out why. This is what my mongo entries look like: { "changes": [ { "name": "oBf4vPN6TcGw8mbok", "date": "2016-06-07T01:48:37.695Z", "score": "general", "value": "5" }, { "name":

问题 How can I query a field in an object? My html retrieves all the objects in array called 'postcards' Meteor.user.profile.postcards [ { _id: 84fh83f, field_one: "a name", field_two: " winter whether", field_three: " lost more writing" }, { _id: 6jsf58s, field_one: "another name", field_two: " topical issues ", field_three: " lost more writing" } ] Note: I used random.Id() so each object in the array can be uniquely identified. Setting a session value to this._id when the user is focused on the

问题 I'm specifically trying to do this client side but it it can only be done server side I will use Meteor.call to return the compiled template as a string via DDP/Ajax. My end goal is to dynamically create new templates (HTML, events, helpers, etc) at runtime. And then sometimes replace existing templates with updated ones. 回答1: The compilation of templates is done on the server, see https://github.com/meteor/meteor/tree/devel/packages/spacebars-compiler I don't think you'd want to do this on

问题 I tried to have a recursive template like this: <template name="generate"> {{#if elements}} {{#each elements}} <div>{{#if elements}}{{> generate}}{{/if}}</div> {{/each}} {{else}} {{> generate elements=getElements}} {{/if}} </template> with the helper: Template.generate.helpers({ getElements: function() { return Elements.find() } }) and the "Elements" data object: [{ _id : "fgQ4GHrrZGFFGWPZQ", elements" : [{ _id : "hY8iAYJC4KBwGKN84", elements : [] }] },{ _id : "rtMNfaQYwqzNTYqoD", elements :

问题 I have a template image where I display images. The image display toggles between canvas and img tags, depending on if the user just created the image or if it is already on server. I toogle between img and canvas using a reactive dictionary called pageSession where I store a boolean reactive variable called displayMode . I have an helper currentDisplayMode used to return displayMode value. So the helper looks like this: Template.image.helpers({ "currentDisplayMode" : function(){ return

问题 Sorry kind of new to the Meteor framework! I Subscribed to two Publish functions. Even if both publish functions target the same Collection, they both have different functions, that I would like to display in one template. How do I achieve this. I have done allot of research but there doesn't seem to be sufficient information on how to achieve. Following are the two publish functions in code that I subscribe to: .server/main.js: Meteor.publish('MerchantTrending', function (categoryMan){ var

问题 I have following code: <div class="form-group {{#if afFieldIsInvalid name='latitude' OR name='longitude'}}has-error{{/if}}">......</div> How can I use AND/OR in if conditions of spacebars templates ? 回答1: Spacebars is an extension of Handlebars, which is designed to be a logic-less template language. The solution is to register a helper. For the general case, see these similar questions: How to do IF logic in HandleBars templates? Include conditional logic in Handlebars templates, or just use

问题 So let's say I'm storing <div>{{name}}</div> and <div>{{age}}</div> in my database. Then I want to take the first HTML string and render it in a template - {{> template1}} which just renders the first string with the {{name}} handlebar in it. Then I want to give that newly generated template/html data, so that it can fill in the handlebar with the actual name from the database, so that we would get <div>John</div> . I've tried doing <template name="firstTemplate"> {{#with dataGetter}} {{>
