dynamic

问题 I'm looking for a way to add a div component in Angular 2 at a specific place (mouse event x/y). https://jsfiddle.net/lennartquerter/w2c7uqw6/ this.xPos = xPos; this.yPos = yPos; i pass the position into my reject class, but i do not know how to make styles out of it ? I checked angular docs but i can only set booleans and fixed css values / classes. I would like to do something like this: [style]="rejectPosition" this.rejectPosition = "left: " + this.xPos + "px ; top: " + this.yPos + "px;"

问题 I have written this code in visual studio 2013 utilizing .net v4.5. The problem I am having is that I am now having to drop down to .net v3.5 and the dynamic keyword is throwing an error as missing an assembly reference. Is there an equivalent type to 'dynamic' in .net v3.5 or a way for me to achieve the same results as below? I thought I may have found my answer here, but var is throwing errors when I add the .Attributes or .Text property modifications. private void CreateControl<T>(string

问题 Just came across an interesting effect while debugging a View. The scenario is easy to reproduce - I have a breakpoint in a View , in the Watch window I add ViewBag.ViewData and the value is null . However, if I just add ViewBag and expand the object, I can see the ViewData and it is not null . I can also successfully expand it and see its properties. Can anyone explain whether it's a bug or what causes this behavior? EDIT ViewBag.ViewData is actually null . E.g. if I have this code in the

问题 Using .NET-4.0, how would I use Dynamic to accomplish the following without using reflection? public void InvokeMethod(string methodName) { Type t = typeof(GCS_WebService); GCS_WebService reflectOb = new GCS_WebService(); MethodInfo m = t.GetMethod(methodName); m.Invoke(reflectOb, null); } 回答1: Dynamic typing in C# doesn't provide for that - the names of the members you want to access still has to be known at compile-time. (You could create the call site yourself of course and use the rest of

问题 I'd like to know how to set the length of multidimensional arrays/create dynamic multidimensional arrays in Pascal. Like SetLength(arr,len) does for one dimensional arrays. I cannot find the answer. 回答1: var arr: array of array of real; ... SetLength(arr, 10, 20); // creates a 10 by 20 matrix A bad, but equivalent, way of doing this is to do SetLength(arr, 10); for i := low(arr) to high(arr) do SetLength(arr[i], 20); The latter approach allows "non-rectangular" arrays, however. 来源： https:/

问题 Let say I have 5 element from PHP query (so it is dynamic) Illustrated below: element 1 class=element id=id_1 element 2 class=element id=id_2 element 3 class=element id=id_3 element 4 class=element id=id_4 element 5 class=element id=id_5 We ussulay use jquery event by knowing their class or id , but in this case, we don't know exactly their id . $("#id_3").click(function() { //in this case we have known we want to add event when we click id_3 }); How to deal with dynamic element from PHP

问题 This question already has answers here : Variable number of predictable for loops in Python (2 answers) Closed last year . Is it possible to add/reduce number of nested for loops in a function based on the length of input? For example: Based on a certain input of length 3, I may need to use 1 nested for loop (for loop inside another for loop). Similar to this, for i in range(0, len(input)+1): for j in range(i+1, len(input)+1): However, when the input length is 4, I could have achieved my

问题 I am currently working on an assignment where I have to extract text one char at a time from each file and then concatenate them and print it out. I have found a way to extract my characters and save them in variable a-d. How do I add these char to my char array to print out to the end? I initially malloc it to the size of a char and at each if statement I realloc. All the guides I found online recommend I use strcat but I cannot pass in the a-d variables to append. How would I fix this?

问题 I have created a tab view, with the following structure: <tabs> <ul #getVCRefHERE > <li>tab1</li> <li>tab2</li> </ul> <tab> <ng-content></ng-content> <!--screen for tab2 --> </tab> <tab> <ng-content></ng-content> <!--content for tab1 --> </tab> </tabs> I create each component: tabs,tab,and the component placed in the ng-content. place. The issue is when I insert at the end of the ViewContainer(it uses ul as it's anchor element) the sequential tabs are nest inside of the tab like this: <tabs>
