Fonctions afterRender, afterAdd ou beforeRemove - callback à appeler par rapport aux éléments DOM restitués - voir Note 4 Remarque 1: Rendu d'un modèle nommé Normalement, lorsque vous utilisez des liaisons de flux de contrôle (foreach, with, if, etc. The reason is afterRender fires once when infuser renders the loadingTemplate and then once when the actual external template is loaded. I want to scroll to a particular item after it has finished rendering. In that case, you can use the As you can see from Example 2 above, it’s possible to use As described in Note 1, you can refer to each array entry using the In some cases, you might want to duplicate a section of markup, but you don’t have any container element on which to put a In this example, there isn’t anywhere to put a normal When you modify the contents of your model array (by adding, moving, or deleting its entries), the Note that reordering detection is not guaranteed: to ensure the algorithm completes quickly, it is optimized to detect “simple” movements of small numbers of array entries.
I am also learning knockout with external templates (same library as you) and mine is also firing twice.
jquery-mobile knockout.js. I was able to use custom bindings in some such situations, but I would not know how to do this here. afterrender bind data foreach observable array list html element current knockout.js - Comment remplacer un élément d'index donné dans knockoutjs Comment remplacer un index donné dans un observableArray par un autre élément.
For example, For example,
So even though I have set the option in my config: infuser.defaults.useLoadingTemplate = false; I'm using a foreach in the list to create each list item. TvdH TvdH. This will cause the data to be re-rendered using the appropriate template.If your function accepts a second parameter, then it will receive the entire In the vast majority of cases, Knockout’s native templating and the Then, you can use jQuery.tmpl syntax in your templates. The binding will output a section of markup for each entry.Alternatively, pass a JavaScript object literal with a property called As shown in the above examples, bindings within the But what if you want to refer to the array entry itself (not just one of its properties)? The data it supplies to the template will be your current model object.For more control, pass a JavaScript object with some combination of the following properties:Normally, when you’re using control flow bindings (It’s not very often that you’ll need to use named templates, but on occasion it can help to minimise duplication of markup.This gives the same result as embedding an anonymous template directly inside the element to which you use A simpler and more elegant option, however, is to use This is mainly useful if you have multiple levels of nested Sometimes you might want to run custom post-processing logic on the DOM elements generated by your templates. Knockout will supply the following parameters to your callback: An array of the inserted DOM elements; The data item against which they are being bound The documentation for foreach details the afterRender event, and has this note: Note: These callbacks are only intended for triggering animations related to changes in a list. If the algorithm detects too many simultaneous reorderings combined with unrelated insertions and deletions, then for speed it can choose to regard a reordering as an “delete” plus an “add” instead of a single “move”, and in that case the corresponding DOM elements will be torn down and recreated. The following example shows that, if your array is observable, then the UI will be kept in sync with changes to that array.Pass the array that you wish to iterate over. For example,Please note that, as of December 2011, jQuery.tmpl is no longer under active development. afterRender — is invoked each time the foreach block is duplicated and inserted into the document, both when foreach first initializes, and when new entries are added to the associated array later. We recommend the use of Knockout’s native DOM-based templating (i.e., the
Knockout makes it easier to create rich, responsive UIs with JavaScript - knockout/knockout For example, if you’re using a JavaScript widgets library such as jQuery UI, you might want to intercept your templates’ output so that you can run jQuery UI commands on it to transform some of the rendered elements into date pickers, sliders, or anything else.Generally, the best way to perform such post-processing on DOM elements is to write a Pass a function reference (either a function literal, or give the name of a function on your view model), and Knockout will invoke it immediately after rendering or re-rendering your template.
