更新
我现在已经解决了这个问题,改变了这一行:
idList.push(this.id);
为:
$(this).attr('id')
我正在尝试遍历我页面上的所有复选框,并将所有已检查的ID添加到数组中。我让它循环遍历每个复选框,并检测它是否被选中,但是我无法将每个选中复选框的ID添加到数组中。
有人能告诉我哪里出错了吗?
感谢。
使用Javascript:
if (element == 'deleteButton' || element == 'allowButton')
{
//For testing.
//alert("Button Clicked");
//Create an empty array, so it can be re-sized at run time.
var idList = [];
//Loop through all checkboxes, adding each ones id to an array.
$('#reported_rages').find('input[type="checkbox"]:checked').each(function () {
//this is the current checkbox
//For testing.
//alert("Checked");
//Add the current ID to the array
idList.push(this.id);
});
//return false; // or do something else.
}
alert(idList);

这里尝试实现这些想法。
/*sets variable to global so it can be accessed outside of function*/
var idList = [];
function run(){
/*clears the original variable*/
idList = [];
$('#data').find('input[type="checkbox"]:checked').each(function () {
idList.push(this.id);
});
/*prints after list is populated*/
console.log(idList);
$('#results').html(idList);
}
/*binds run function to click of submit*/
$('#submit').click(run);
