jQuery Add Key Value Pair to an Empty Object
提问by VIDesignz
In jQuery, I can add multiple attributes to an element like so...
在jQuery中,我可以像这样向元素添加多个属性......
var input = $('<input/>').attr({ type : 'text', value : 'New Value'});
My question is, how can I achieve this using a variable like this...
我的问题是,我怎样才能使用这样的变量来实现这一点......
var input = $('<input/>').attr(inputAttr);
I was under the assumption that inputAttrshould be an object and that I could add to that object. I must be mistaken. This was one of my many attempts to make this happen.
我假设它inputAttr应该是一个对象并且我可以添加到该对象中。我一定是弄错了。这是我为实现这一目标所做的众多尝试之一。
var inputAttr = {};
inputAttr.add({ type: 'text' });
inputAttr.add({ value : 'New Value' });
I also tried like this....
我也这样试过......
var inputAttr = {};
inputAttr.add('type: text');
inputAttr.add('value : New Value');
I thought maybe inputAttrshould be an array instead, which seems to output a correct string but not sure how to make it an object (which I think it should be).
我想也许inputAttr应该是一个数组,它似乎输出了一个正确的字符串,但不确定如何使它成为一个对象(我认为它应该是)。
var inputAttr = [];
inputAttr.push('type: text');
inputAttr.push('value : New Value');
// Then added object brackets like so
var input = $('<input/>').attr({inputAttr});
Any help would be appreciated! Thank you in advance!
任何帮助,将不胜感激!先感谢您!

Object properties are just accessed by name. It is not an array.
对象属性仅通过名称访问。它不是一个数组。
var inputAttr = {};
inputAttr.type = 'text';
inputAttr.value = 'New Value';
var input = $('<input/>').attr(inputAttr);
If you want to access them indirectly via keys it is like a dictionary:
如果你想通过键间接访问它们,它就像一本字典:
var inputAttr = {};
inputAttr["type"] = 'text';
inputAttr["value"] = 'New Value';
