jquery和jqueryui：使用resizable后设置宽度不工作？ [英] Jquery and Jqueryui: set width not working after using resizable?
问题描述
我在display：block中有一组div，当文档准备就绪时，我使用javascript和jqueryui来显示任务的持续时间。 ：
1）将子div添加到块div
2）使子div可拖动并调整大小
这可以正常工作。
我也想预设divs宽度（任务持续时间），但是有一个奇怪的行为：div在文档加载后不能调整大小。然而，只要我点击div边框来调整它的大小，宽度就会弹出到我在脚本中使用的值。
以下是简化的HTML
p> < div id =gridcontainer>
< div id =railing_1class =railing>< / div>
< div id =railing_2class =railing>< / div>
< / div>
这里是html文档头部的JS：
< script type =text / javascriptsrc =http://code.jquery.com/jquery-1.9.1.js><<<< ; /脚本>
< script type =text / javascriptsrc =http://code.jquery.com/ui/1.10.2/jquery-ui.js>< / script>
< script type =text / javascript>
var displayRange = {slots：24，unit：h，start：0};
var taskList = {
tasks：[
{id：1，line：1，start：0，duration）： 72}，
{id：2，line：1，start：73，duration：48}，
{id ：3，line：2，start：0，duration：120}
]
};
< / script>
< script type =text / javascript>
$（）。ready（function（）{
var railingId;
var taskId;
var jTaskId;
var oNewP;
var oText;
var displayRange = {slots：24，unit：h，start：0};
var taskList = {
tasks：[
{id：1，line：1，start：0，duration：72}，
{id：2， line：1，start：73，duration：48}，
{id：3，line：2，start： 0，duration：120}
]
};
//获取任务列表并创建/追加子元素到每行
for（var i = 0; i< taskList.tasks.length; i ++）{
//alert（taskList.tasks[i].duration）;
railingId =railing_+ taskList.tasks [i] .line ;
taskId =task_+ taskList.tasks [i] .id;
oNewP = document.createElement（div）;
oText = document.createTextNode（taskList.tasks [i] .id）;
oNewP.setAttribute（id，taskId）;
oNewP.setAttribute（class，taskbar）;
oNewP.appendChild（oText）;
document.getElementById（railingId）.appendChild（oNewP）;
jTaskId =＃+ taskId;
$（jTaskId）
.draggable（{
grid：[24，44]，
containment：#gridcontainer，
axis：x，y
}）
.resizable（{
grid：[24，0]，
句柄：e，w，
containment：#gridcontainer
}）;
}
}）;
/ *
这里是我尝试预设其中一个任务的例子;我也
尝试使用$（'＃task_2'）。width（100）;
但无效
* /
$（'＃task_2'）。css（width，100px）;
< / script>
我为这个问题设置了一个Jsfiddle：
您会注意到，如果您尝试调整数字2的大小，它将弹出100px，然后它可以根据可调整大小的网格（24px）进行大小调整。 $ b
当然，我想要任务2预设为100 ...
有什么想法？
对于乱七八糟的代码抱歉。
编辑
这似乎与Jquery没有任何关系 - 我尝试简单地使用Javascript宽度和setAttribute方法，而不关心JQ - 但结果是没有调整大小。
关于JQ的互动部分是，当我点击调整大小时，div弹出到所尝试的大小 - 这似乎表明文档没有正确重新加载（??），当我单击div时，一些魔术发生了。
INLINE ELEMENTS没有宽度，所以这不是Javascript问题。问题在于CSS定义。

I am writing a grid to show task durations.
I have a set of divs in a display:block and when document is ready I use javascript and jqueryui to: 1) add child divs to the block divs 2) make the child divs draggable and resizable This works fine. I would also like to preset the divs width (the task duration), but there is a strange behavior: the divs do not resize after the document is loaded. However as soon as I click on the div border to resize it, the width "pops" to the value I used in the script.
Here is the simplified HTML
<div id="gridcontainer">
<div id="railing_1" class="railing"></div>
<div id="railing_2" class="railing"></div>
</div>
And here is the JS on the head of the html doc:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript" src="http://code.jquery.com/ui/1.10.2/jquery-ui.js"></script>
<script type="text/javascript">
var displayRange = { "slots": "24", "unit":"h","start":"0" };
var taskList = {
"tasks": [
{ "id":"1" , "line":"1", "start":"0","duration":"72" },
{ "id":"2" , "line":"1", "start":"73","duration":"48" },
{ "id":"3" , "line":"2", "start":"0","duration":"120" }
]
};
</script>
<script type="text/javascript">
$().ready(function(){
var railingId;
var taskId;
var jTaskId;
var oNewP;
var oText;
var displayRange = { "slots": "24", "unit":"h","start":"0" };
var taskList = {
"tasks": [
{ "id":"1" , "line":"1", "start":"0","duration":"72" },
{ "id":"2" , "line":"1", "start":"73","duration":"48" },
{ "id":"3" , "line":"2", "start":"0","duration":"120" }
]
};
//get the task list and create/append the children to each line
for(var i = 0; i<taskList.tasks.length; i++){
//alert(taskList.tasks[i].duration);
railingId = "railing_" + taskList.tasks[i].line;
taskId = "task_" + taskList.tasks[i].id;
oNewP = document.createElement("div");
oText = document.createTextNode(taskList.tasks[i].id);
oNewP.setAttribute("id",taskId);
oNewP.setAttribute("class","taskbar");
oNewP.appendChild(oText);
document.getElementById(railingId).appendChild(oNewP);
jTaskId = "#" + taskId;
$(jTaskId)
.draggable({
grid: [ 24, 44 ],
containment: "#gridcontainer",
axis: "x, y"
})
.resizable({
grid: [ 24, 0 ],
handles: "e, w",
containment: "#gridcontainer"
});
}
});
/*
Here is where I try to preset one of the tasks as an example; I've also
tried using $('#task_2').width("100");
but didn't work
*/
$('#task_2').css("width","100px");
</script>
I've set a Jsfiddle with the problem:
You'll notice that if you try to resize number 2, it pops 100px, then it is able to resize according to the resizable grid (24px)
Of course, I would like task 2 to be preset as 100...
Any ideas?
Apologies for the messy code.
EDIT This doesn't seem to have anything to do with Jquery -- I've tried simply using Javascript width and setAttribute methods, without caring about JQ -- but the result is no resize. The interesing part about JQ is that when I click to resize, the div pops to the attempted size -- which seems to indicate the document is not "reloading" properly (??) and when I click the div, some magic happens.
Root of the issue found on this Stackoverflow thread:
display:inline resets height and width
INLINE ELEMENTS do not have width, so this is not a Javascript problem. The issue was with the CSS definition. Removed the display: inline instruction and it worked fine.
