我只想保护一个手柄的纵横比。我尝试使用此代码运行它,但它没有帮助我。你有任何解决方案吗?
$( "#resizable").resizable({
handles: 'se,e,w',
aspectRatio: true,
start: function(e,ui) {
if (jQuery(e.originalTarget).hasClass("ui-resizable-se")) {
aspectRatio: false;
}
}
});
特别感谢任何解决方案..

关于这个错误有很多未解答的问题。
以下是适合您的解决方案:)
<script>
var changedRatio = "DK"; //DK->dont keep
var nowResizing = "NO";
$(function() {
$('#resizable').resizable({
start:function(event,ui){
nowResizing = "YES";
},
stop:function(event,ui){
nowResizing = "NO";
}
});
$(document).on('mouseenter', '.ui-resizable-e', function(){
if(changedRatio!="DK"){
if(nowResizing!="YES"){
var targetDiv = $(this).parent().attr("id");
dontKeep(targetDiv);
}
}
});

一个对我有用的简单解决方案
var is_se = ($(this).data('uiResizable').axis == "se");
$(this).resizable( "option", "aspectRatio", is_se ).data('uiResizable')._aspectRatio = is_se;

略微变化对我有用,可能是因为更新版本的jQuery。四个角的把手将保持纵横比,而侧面的把手则不会。
$elements.resizable({
handles: "all",
start: function(event, ui) {
var handle = $(this).data('ui-resizable').axis;
// We should maintain the aspect ratio for corners, not for sides
var maintain_aspect_ratio = (["n", "e", "s", "w"].indexOf(handle) == -1);
$(this).resizable( "option", "aspectRatio", maintain_aspect_ratio )
.data('ui-resizable')
._aspectRatio = maintain_aspect_ratio;
},
...

我认为你应该提供宽高比而不是true
。
aspectRatio: 16 / 9
OR
aspectRatio: 4 / 3
参考http://jqueryui.com/resizable/#aspect-ratio
OR
$( "#resizable:not(ui-resizable-se)").resizable({
handles: 'se,e,w',
aspectRatio: 16/9
});
