[英]Access JS object inside jquery each() iterator function
$('input.ISSelectSearch').each(function(i) {
var box = new Object;
box.size = 80;
box.width = 110;
//CODE CODE CODE
});
How can I access the value of box
which was set in the previous iteration? 如何访问上一次迭代中设置的
box
的值? Alternatively, is it possible to access it via a key of some kind? 或者,是否可以通过某种键访问它?
$('input.ISSelectSearch').each(function(i) {
var box = new Object;
box.size = 80;
box.width = 110;
prevsize = $(this).box[/* previous iteration element id or name */].size
//CODE CODE CODE
});
The problem is that I need to know the data associated with each 'input.ISSelectSearch'
element box so that I can change them depending on the values of the current or preceding box objects. 问题是我需要知道与每个
'input.ISSelectSearch'
元素框关联的数据,以便我可以根据当前或前面的框对象的值来更改它们。 In other words I need a connection between the element box objects so that I can specify certain changes in one based on the values of another. 换句话说,我需要元素框对象之间的连接,以便我可以根据另一个的值指定一个更改。
you can do something like this 你可以做这样的事情
var pre = null;
$('input.ISSelectSearch').each(function(i) {
var box = new Object;
box.size = 80;
box.width = 110;
//condition so that first time it dosent shows an error
if(pre!=null){
//CODE
}
pre = this;
//CODE CODE CODE
});
EDIT AFTER THE COMMENT:- 编辑后编辑: -
probably you wanna use $.data() method 可能你想使用$ .data()方法
this was you can associate the data with the element 这是您可以将数据与元素相关联
so inside the loop you can do 所以在循环内你可以做到
$('input.ISSelectSearch').each(function(i) {
var box = new Object;
box.size = 80;
box.width = 110;
$('input.ISSelectSearch').data(i,box);
//and now you can retrive the data whenevr you want
var olderObject = $('input.ISSelectSearch').data(SOME_OLDER_INDEX)
});
You can do it with index if you like 如果您愿意,可以使用索引来完成
var $This = $('input.ISSelectSearch');
$This.each(function (index, value) {
var Pre;
var box = { size: 80, width: 110 };
if (index > 0) {
Pre = $This[index - 1];
//Your code hear
} else {
//otherwise
}
});
