我想将一个对象传递给函数flipIt(obj)。我将图像ID存储在名为globe的变量中。

当我将globe传递给flipIt()时,它不起作用,因为globe是包含图像ID的变量,并且flipIt()需要一个对象。

我已经尝试过将('#'+globe)设置为obj,但它也无法正常工作:

flipIt('#'+globe);


函数定义为:

function flipIt(obj) {
    console.log("value before Function status   " + status);
    alert('FlipIT Called' + obj);

    $(obj).css("-webkit-transform-style","preserve-3d");
    $(obj).css("-webkit-transition","all 1.0s linear");
    $(obj).css("transform-style","preserve-3d");
    $(obj).css("transition","all 1.0s linear");
}


我尝试通过打印obj值来尝试...对于变量,它正在打印id值,而不是应该打印HTMLimage元素。

Java脚本

$(document).ready(function () {
    var globe;

    /*   Reading the data from XML file*/
    $.ajax({
        type: "GET",
        url: "photos.xml",
        dataType: "xml",
        success: function(xml) {
            $(xml).find('item').each(function() {
                var path = $(this).attr('path');
                var width = $(this).attr('width');
                var height = $(this).attr('height');
                var id = $(this).attr('id');
                var alt = $(this).attr('alt');
                var longdesc = $(this).find('longdesc').text();
                var description = $(this).find('desc').text();
                $('#myImageFlow').prepend('<img src="'+path+'" id='+id+'  height="'+height+'"  width="'+ width+'" longdesc="'+longdesc+'" alt="'+alt+'"/>');
                imgArr[i] = description;
                i = i+1;
            });
        });
    });
});

最佳答案

假设globe是包含要选择的元素的id的字符串(不带#前缀),则需要先将其转换为jQuery对象,然后再将其传递给函数:

flipIt($('#'+globe));


然后,您无需在$()函数内将另一个flipIt包裹起来,因为它已经是一个对象。因此,在函数内部,只需执行以下操作:

obj.css("-webkit-transform-style","preserve-3d");
...


接下来,我想您想在全局范围内声明globe。现在,您在文档准备功能的范围内声明它。所以放在外面:

var globe;

$(document).ready(function () {
    // document ready
});


准备好了的文档也有一个较短的符号:

$(function() {
    // document ready
});
