[英]How to add a property to an element?
Keeping in mind the addition of .prop() in jQuery replacing .attr() for many boolean type attributes/ properties of an element. 请记住,在jQuery中添加了.prop(),以将.attr()替换为元素的许多布尔类型属性/属性。 My question is how to add a 'Property' in the following code?
我的问题是如何在以下代码中添加“属性”?
The following set of code is functionally doing what I require it to do, but in my browser debug section I see a warning "JQMIGRATE: jQuery.fn.attr('selected') may use property instead of attribute" referring jquery-migrate-1.2.1.js 以下代码集在功能上正在执行我需要执行的操作,但是在我的浏览器调试部分中,我看到一条警告“ JQMIGRATE:jQuery.fn.attr('selected')可能使用属性而不是属性”,引用了jquery-migrate- 1.2.1.js
$("<select />",{
"class": "align-select",
id: "align_select_123"
}).append(
$("<option />",{
value: "left",
selected: "selected",
html: "Left"
}),
$("<option />",{
value: "right",
html: "Right"
}),
$("<option />",{
value: "centre",
html: "Centre"
}),
$("<option />",{
value: "justify",
html: "Justified"
})
)
The above mentioned warning refers to the 7th line of the code ie selected: "selected". 上面提到的警告是指代码的第7行,即已选择:“已选择”。 What is the possible good way to get same code working with out generating this warning?
在不生成此警告的情况下获得相同代码的可能的好方法是什么?
I have tired: 我累了:
$("<option />",{
value: "left",
html: "Left",
selected
})
but it didn't worked!! 但是没有用!
Although I would still use the attribute in this context for readability (since it's true that prop should be used), to set the property would be in an other call : 尽管我仍会在此上下文中使用该属性以提高可读性(因为确实应该使用prop),但是要在另一个调用中设置该属性:
$("<option />",{
value: "left",
html: "Left",
}).prop('selected', true),
Have you tried like this ? 你有这样尝试过吗?
$("<option />", {
value : "left",
selected: "selected",
html : "Left"
}
