Get all input types with name, id, value in JQuery
提问by Pradip
In JQuery, how can i get list of input type with name, id and value present in any div?
在 JQuery 中，如何获取任何 div 中存在的名称、ID 和值的输入类型列表？

Selects inputs that descend from a div that have both name, id, and value attributes present. Then pushes the "type" attribute of each matching item into an array.
选择从具有名称、ID 和值属性的 div 下降的输入。然后将每个匹配项的“type”属性推入一个数组。
var inputTypes = [];
$('div input[name][id][value]').each(function(){
inputTypes.push($(this).attr('type'));
});

This?
这个？
var inputTypes = [];
$('input[name!=""][value!=""][id!=""]').each(function() {
inputTypes.push($(this).prop('type'));
});
The property!=""is necessary than just [property], this is to filter out things like
这property!=""不仅仅是必要的[property]，这是过滤掉诸如
<input type="text" name="something" value="" id="someId" />
<input type="text" name="something" value="" id="someId" />
(Which I assume you don't want to get input with any property equals to empty string)
（我假设您不想获得任何属性等于空字符串的输入）

You can look at each input, get their attributes and check against an empty string for each. You could use any method you want to present them, here I'm just adding them to an array.
您可以查看每个输入，获取它们的属性并检查每个输入的空字符串。你可以使用任何你想展示它们的方法，在这里我只是将它们添加到一个数组中。
var inputs = new Array();
$("input").each(function() {
var name = $(this).attr("name");
var id = $(this).attr("id");
var val = $(this).val();
if ((name) && name !== "") && ((id) && id !== "") && ((val) && val !== "")) {
inputs.push(this);
}
});

You can get access for input by:
您可以通过以下方式获得输入权限：
$('input')
then get attributes which you want by for example .attr('type'), .attr('id'). And if you need list write them into array is $('input').each(...);
然后通过例如.attr('type')，获取您想要的属性.attr('id')。如果你需要列表将它们写入数组是$('input').each(...);

When You want to select an input with an specific name like "foo"do it as below :
当您想选择具有特定名称的输入时，"foo"请执行以下操作：
$('div input[name="foo"]').each(function(){
// your program logic goes here
// this.val("123")
});
Or you might wanna get ones which their value does not match "123":
或者你可能想得到那些它们的价值不匹配的"123"：
$('div input[value!="123"]').each(function(){
// your program logic goes here
});
Or even a combination of both :
或者甚至是两者的结合：
$('div input[name="foo"][value!="123"]').each(function(){
// your program logic goes here
});
