javascript - js 根据src的数量创建img标签?
html部分:
<code> <div class="comb"> <img src="/static/imghw/default1.png" data-src="image1.jpg" class="lazy" alt=""> <img src="/static/imghw/default1.png" data-src="/img/bVsduG" class="lazy" alt=""> <img src="/static/imghw/default1.png" data-src="/img/bVsduG" class="lazy" alt=""> <img src="/static/imghw/default1.png" data-src="/img/bVsduG" class="lazy" alt=""> <img src="/static/imghw/default1.png" data-src="/img/bVsduG" class="lazy" alt=""> </div> </code>
JS代码:
<code> function preloader(){ // create object imageObj = new Image(); // set image list images = new Array(); images[0]="image1.jpg"; images[1]="image2.jpg"; images[2]="image3.jpg"; images[3]="image4.jpg"; // start preloading for(var i=0; i</code>
显示效果:
问题:
preloader()这个方法动态设置了src,那么html中的img元素能不能根据src的数量有多少就创建多少个img呢?
一般在做动态创建图片这种需求都是怎么解决的?
求思路或建议!

先打印图片src源;
根据src源创建
将
放置到目标dom里
<code> function preloader(){ // set image list var images = ["image1.jpg", "image2.jpg", "image3.jpg", "image4.jpg"]; // start preloading for(var i=0; i</code>
把preloader动态直接修改dom换成 preloader先创建img 字符串,把多个img字符串作为innerHTML再插入到dom中
如果用mvvm框架的话,比较好解决。 model生成了多少的src, 视图自动repeat 循环加载img图片
要不采用模板的方式,主动repeat 循环加载img图片
做一个div,里面放img标签就可以了,根据你获得的图片数量创建。不过这样写很奇怪,如果是静态页面没有太好的解决方式,可以参考下backbone.js,应该有所帮组

How to use the Bootstrap button? Introduce Bootstrap CSS to create button elements and add Bootstrap button class to add button text

To adjust the size of elements in Bootstrap, you can use the dimension class, which includes: adjusting width: .col-, .w-, .mw-adjust height: .h-, .min-h-, .max-h-

In PHP, the final keyword is used to prevent classes from being inherited and methods being overwritten. 1) When marking the class as final, the class cannot be inherited. 2) When marking the method as final, the method cannot be rewritten by the subclass. Using final keywords ensures the stability and security of your code.

The file upload function can be implemented through Bootstrap. The steps are as follows: introduce Bootstrap CSS and JavaScript files; create file input fields; create file upload buttons; handle file uploads (using FormData to collect data and then send to the server); custom style (optional).

There are several ways to insert images in Bootstrap: insert images directly, using the HTML img tag. With the Bootstrap image component, you can provide responsive images and more styles. Set the image size, use the img-fluid class to make the image adaptable. Set the border, using the img-bordered class. Set the rounded corners and use the img-rounded class. Set the shadow, use the shadow class. Resize and position the image, using CSS style. Using the background image, use the background-image CSS property.

The default style of the Bootstrap list can be removed with CSS override. Use more specific CSS rules and selectors, follow the "proximity principle" and "weight principle", overriding the Bootstrap default style. To avoid style conflicts, more targeted selectors can be used. If the override is unsuccessful, adjust the weight of the custom CSS. At the same time, pay attention to performance optimization, avoid overuse of !important, and write concise and efficient CSS code.

Answer: You can use the date picker component of Bootstrap to view dates in the page. Steps: Introduce the Bootstrap framework. Create a date selector input box in HTML. Bootstrap will automatically add styles to the selector. Use JavaScript to get the selected date.

To verify dates in Bootstrap, follow these steps: Introduce the required scripts and styles; initialize the date selector component; set the data-bv-date attribute to enable verification; configure verification rules (such as date formats, error messages, etc.); integrate the Bootstrap verification framework and automatically verify date input when form is submitted.
