问题 The webpage that I'm testing is using knockout. On other pages on our site that are not currently using knockout I'm not having the same problem. The scenario I have is where the page opens, I enter in various required fields and click the save button. At some point between when it enters a value in the last text field and when it clicks the save button the fields that previously had values become cleared out, and thus the script can't continue. Here is an example of the code that I'm running

问题 I am in the process of porting some javascript code to typescript and using requirejs.

问题 I'm trying to POST a JSON object (a JSON-ified knockout model, if that's of any relevance) to my MVC controller, and have the controller return a new view. To do this, I'm sending the data with a form. The problem is that I would like to have the JSON automatically converted to a model when the controller receives it. If I were to use an AJAX call for this, var actionModel = new Object(); actionModel.Controls = ko.toJS(self.controls()); var json = JSON.stringify(actionModel); $.ajax({ url:

问题 I'm writing a webpage, which will fully support mobile browsers. The page currently uses KnockoutJS to dynamically recalculate component sizes (and hide some components) based on the screen (or container) size. I have a problem with the android browser: When you click on a text field, the pop up keyboard causes a screen resize, which causes KnockoutJS to (correctly) re-render the display. This momentarily causes the text field to lose focus, which pop-up keyboard to disappear. If only I could

问题 Using knockout.js, is it possible to bind to a property of a child object of a JSON object from the server? Specifically, if I'm given an object from the server that looks like this: var obj = { list: [ { key: "a", value: 1 }, { key: "b", value: 2 }, { key: "c", value: 3 } ], selected: { key: "", value: null } }; I create a viewModel from this javascript object via the "mapping" plugin: var viewModel = ko.mapping.fromJS(obj); And I bind list to a <select> tag like so: <select data-bind=
