问题 Facing a problem with JavaScript Date function, returns "Date {Invalid Date}" in Firefox browser but works fine in Google chrome. // My Input is new Date("Sat Jan 01 00:00:00 EST 1"); // Works fine in google chrome // Result: Mon Jan 01 2001 10:30:00 GMT+0530 (India Standard Time) // Not working in Firefox (Version: 15.0.1) // Result: Date {Invalid Date} 回答1: Date does not take a timezone parameter in that way. My thought is that Chrome is just ignoring it. new Date(year, month, day [, hour,

问题 I want my razor view to look something like this @Ajax.ActionLink("A", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-A" }) @Ajax.ActionLink("B", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-B" }) @Ajax.ActionLink("C", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-C" }) and my javascript to look something like this function updateLetter

问题 This is a part of my Edit view: <dt> @Html.LabelFor(model => model.MainModel.StartDate) </dt> <dd> @Html.TextBoxFor(model => model.MainModel.StartDate) @Html.ValidationMessageFor(model => model.MainModel.StartDate) <div class="targetDiv"> My content </div> </dd> So as all of you know when StartDate field in my model not valid unobtrusive show the error message and if valid hide it. Now I want to add another action to this process. I need if StartDate value is Invalid show "targetDiv" div and

问题 I am using asp.net mvc 3 jquery validate unobstructive javascript. I am trying to write all my validation on the serverside through annotations and then have the new feature of mvc 3 take care of the client side. I have a dialog that has a button on it(just a button not a submit button) that I want to post data to the server through ajax. So when the user clicks on the button I do a form submit and return false to cancel the post back. I thought that would trigger the validation but that does

问题 Given an Array Literal inside a JavaScript Object, accessing its own object's properties does not seem to work: var closure = { myPic : document.getElementById('pic1'), picArray: [this.myPic] } alert(closure.picArray[0]); // alerts [undefined] Whereas declaring an Array Item by accessing an other JavaScript Object seem to work ​var closure1 = { ​ ​ myPic : document.getElementById('pic1') ​} ​ ​var closure2 = { ​ ​ picArray: [closure1.myPic] ​} ​ ​alert(closure2.picArray[0]); // alerts [object

问题 I would like to know if the module pattern or Constructor/protoType pattern is more applicable to my work. Basically I am using unobtrusive javascript -- the HTML document has a reference to the .js file. My understanding of the module pattern: call an INIT method (which is basically a public method i can create and return using the module pattern) In the INIT method, assign all click events etc. This sounds like the perfect pattern for my situation, as I don't need to create Objects and

问题 It is always recommended to avoid inline Javascript codes by putting all codes in a JS file, which is included in all pages. I wonder, if this does not cause performance problem in heavy pages. For example, imagine that we have tens of functions like this function function1(element){ var el=document.getElementsByClassName(element); var size=el.length; if(size==0) return; for(i=0;i<size;i++){ // the process } } on every page, we need to run the functions to know if there are corresponding

问题 I know that is the reason some people don't approve of them, but does it really matter? I think that the power that they provide, in interacting with JavaScript and storing and sending information from and to the server, outweighs the validation concern. Am I missing something? What are the ramifications of "invalid" HTML? And wouldn't a custom DTD resolve them anyway? 回答1: The ramification is that w3c comes along in 2, 5, 10 years and creates an attribute with the same name. Now your page is

问题 (my first SO question, so please be kind!) Each Schedule has only one System; Each System has many Applications; Each Application has many Users and Documents. What I want to do to create a Schedule entry: Generate a form that first shows multiple System names that can be clicked. When a System is clicked, it opens a partial that lists Applications associated with that System. Then, when clicking particular Applications, yet another partial opens that contains Users and Documents associated
