问题 This is my first attempt to write anything in javascript, although this does exactly as intended, I am sure it can be done simpler. Not that this script is all that useful, just an exercise in learning something new. I was also trying not to use the evil document write. So what is the more elegant way of doing this? <html> <body> <input name="abc" type="text" id="foo"> <button onclick="AddInputValue()">Submit</button> <p id="displayURL"></p> <script> function AddInputValue(){ var domain =

问题 So I'm trying to append a char to a char* . For example I have char *word = " "; I also have char ch = 'x'; I do append(word, ch); Using this method.. void append(char* s, char c) { int len = strlen(s); s[len] = c; s[len+1] = '\0'; } It gives me a segmentation fault, and I understand why I suppose. Because s[len] is out of bounds. How do I make it so it works? I need to clear the char* a lot as well, if I were to use something like char word[500]; How would I clear that once it has some

Numpy append: Automatically cast an array of the wrong dimension

阅读更多关于 Numpy append: Automatically cast an array of the wrong dimension

问题 is there a way to do the following without an if clause? I'm reading a set of netcdf files with pupynere and want to build an array with numpy append. Sometimes the input data is multi-dimensional (see variable "a" below), sometimes one dimensional ("b"), but the number of elements in the first dimension is always the same ("9" in the example below). > import numpy as np > a = np.arange(27).reshape(3,9) > b = np.arange(9) > a.shape (3, 9) > b.shape (9,) this works as expected: > np.append(a,a

问题 I want to know how to add or append a new element to the end of an array. Is any simple way to add the element at the end? I know how to use a StringBuffer but I don't know how to use it to add an element in an array. I prefer it without an ArrayList or list. I wonder if the StringBuffer will work on integers. 回答1: You can not add an element to an array, since arrays, in Java, are fixed-length. However, you could build a new array from the existing one using Arrays.copyOf(array, size) :

jQuery append() 方法中可以直接添加字符，如：$("p").append(" <b>Hello world!</b>"); 怎么用js实现呢： appendHTML: HTMLElement.prototype.appendHTML = function(html) { var divTemp = document.createElement("div"), nodes = null // 文档片段，一次性append，提高性能 , fragment = document.createDocumentFragment(); divTemp.innerHTML = html; nodes = divTemp.childNodes; for (var i=0, length=nodes.length; i<length; i+=1) { fragment.appendChild(nodes[i].cloneNode(true)); } this.appendChild(fragment); // 据说下面这样子世界会更清净 nodes = null; fragment = null; }; prependHTML: var prependHTML = function(el, html) { var divTemp = document.createElement(

问题 I used the following jQuery example which works like a charm. However it appends the results. What do I need to change to replace the results instead of appending? 回答1: you could empty the element before you append $("#results").empty().append(myHtml); or use the html method $("#results").html(myHtml) 回答2: Just change $('#results').append(myHtml); to $('#results').html(myHtml); 回答3: ok, last entry 2009, but if the problem still exist: $("#results").replaceWith(yourContent) 回答4: Empty function
