How to use img ng-src in AngularJS on android phone?

阅读更多关于 How to use img ng-src in AngularJS on android phone?

问题 The most relevant Q & A I've found is from google groups and I've read the AngularJS docs for ngSrc. I'm trying to use Angular UI Bootstrap - Carousel in my app and I noticed the demo uses absolute URLs for slides like this: image: 'http://placekitten.com/' + newWidth + '/300' . It works on my localhost (mac) but I don't think images (slides) display on my android google nexus phone because I only use relative image paths like this: image: '/images/help/hello-1.jpg' . How can I use relative

new Image 读取宽高为0——onload

阅读更多关于 new Image 读取宽高为0——onload

获取图片一张图片的大小 let img = new Image() img.src = imgUrl if ( img.width != 375 || img.height != 200 ) { message.error(‘请上传375*200大小的图片’) return false } 发现有时img的宽高读取都为0，但是图片url地址是正确的。这边存在一个问题，当给img赋值src 的时候，其实是去请求了这个url获取图片资源，但是在执行img.width != 375 || img.height != 200 这行代码的时候，有可能图片资源尚未请求到，所以自然读取的数值为0. 解决的方法是在确保图片已经被加载后(onload)，再执行对应的方法： var img = new Image() var img1 = new Image(100, 100) //注意onload写在src赋值前比较好 img.onload = () =>{ console.log(img.width, img.height) //210 92 console.log(img1.width, img1.height) //100 100 } img.src = './1.png' img1.src = './1.png' 参照： https://blog.csdn.net/yezi_Z

Multiple Iframes sending ONE request to the same SRC

阅读更多关于 Multiple Iframes sending ONE request to the same SRC

问题 I was wondering if there was a way to have say 3 iframes load the same resource (http://myservice.php) with ONLY ONE request from the iframe. The myservice.php returns an Html Document and the browser should somehow load the html without reloading everything 2 additional times including CSS and JS in the loaded HTML document. In other words, is it possible with ONLY 1 request sent from the 1st iframe to load the HTML document from myservice.php, and have the other 2 iframes load the same html

Replace a featured image's src with the src of the image clicked on

问题 I'm attempting to replace a featured image on a page with any image clicked on in the .gallery div. This will be used on multiple pages in my site so I'd like it to be agnostic of the number of images in the gallery (as that will vary) and where in the gallery the image falls. Is there a way to simply grab the src of the clicked image and replace the src of another image with it? I've dug through a few other topics here on Stack Overflow and pieced together the following code based on them,

Session works in one page but not another

阅读更多关于 Session works in one page but not another

问题 I am working in a php charting package. I start with a form.html that sends to an answer.php page. The answer.php creates the SESSION. Then a required test.php page picks up the session but the required graph.php page does not. I cannot transfer my data from the form to the graph. The required phplot.php is the graph engine and is not needed in the SESSION thread. I have spent five days researching and testing with no luck. I have switched the coding around many times. I'm hoping that someone

PHP Regex Replace Image SRC Attribute

阅读更多关于 PHP Regex Replace Image SRC Attribute

问题 I'm trying to find a regular expression that would allow me replace the SRC attribute in an image. Here is what I have: function getURL($matches) { global $rootURL; return $rootURL . "?type=image&URL=" . base64_encode($matches['1']); } $contents = preg_replace_callback("/<img[^>]*src *= *[\"']?([^\"']*)/i", getURL, $contents); For the most part, this works well, except that anything before the src=" attribute is eliminated when $contents is echoed to the screen. In the end, SRC is updated

Remeber iFram SRC when refreshing parent page

问题 I have an intranet I am building, and am learning web languages as I go. I have a basic html/php page that contains an iFrame, which most of my content is loaded into. I also have a login box that is a popup modal within the main page. When you fill in this popup and hit login, it refreshes the main page, so that it knows you are logged in, and can display your name etc etc. However, this means that the iframe SRC also resets to its default. Is there a way to retain whatever the current SRC
