我想开始讨论使用jQuery的图像大小调整。
这是我的贡献：但我认为我远离解决方案。
怎么样的播种？
谁能帮我？
$(document).ready(function() {
$('.story-small img').each(function() {
var maxWidth = 100; // Max width for the image
var maxHeight = 100; // Max height for the image
var ratio = 0; // Used for aspect ratio
var width = $(this).width(); // Current image width
var height = $(this).height(); // Current image height
// Check if the current width is larger than the max
if(width > maxWidth){
ratio = maxWidth / width; // get ratio for scaling image
$(this).css("width",maxWidth); // Set new width
$(this).css("height",height * ratio); // Scale height based on ratio
height = height * ratio; // Reset height to match scaled image
}
// Check if current height is larger than max
if(height > maxHeight){
ratio = maxHeight / height; // get ratio for scaling image
$(this).css("height",maxHeight); // Set new height
$(this).css("width",width * ratio); // Scale width based on ratio
width = width * ratio; // Reset width to match scaled image
}
});
});
解决方法
您需要在第一个条件后重新计算宽度和高度。这里是整个脚本的代码：
$(document).ready(function() {
$('.story-small img').each(function() {
var maxWidth = 100; // Max width for the image
var maxHeight = 100; // Max height for the image
var ratio = 0; // Used for aspect ratio
var width = $(this).width(); // Current image width
var height = $(this).height(); // Current image height
// Check if the current width is larger than the max
if(width > maxWidth){
ratio = maxWidth / width; // get ratio for scaling image
$(this).css("width",height * ratio); // Scale height based on ratio
height = height * ratio; // Reset height to match scaled image
}
var width = $(this).width(); // Current image width
var height = $(this).height(); // Current image height
// Check if current height is larger than max
if(height > maxHeight){
ratio = maxHeight / height; // get ratio for scaling image
$(this).css("height",width * ratio); // Scale width based on ratio
width = width * ratio; // Reset width to match scaled image
}
});
