Get a List of the Selected Values in a ListBox
提问by DCShannon
There's already a question with a ton of votes for getting the selected value from a dropdown using jQuery here.
已经有一个关于使用 jQuery here从下拉列表中获取所选值的问题。
That answer almost works for a listbox, but if multiple values are selected, the result is a single string with all the values concatenated. This is not useful. I need a collection (list, array, whatever) of the text values for each selected option.
该答案几乎适用于列表框，但如果选择了多个值，则结果是将所有值连接在一起的单个字符串。这没有用。我需要每个选定选项的文本值的集合（列表、数组等）。
At the moment I'm thinking I'll use most of the answer from that other question, but without the .text()at the end, and then iterate through the matches. Better ideas?
目前我想我会使用其他问题的大部分答案，但最后没有.text()，然后遍历匹配项。更好的想法？

You can take multiple selected textby iterating loop as mentioned below.
您可以通过如下所述的迭代循环来获取多个选定的文本。
$('#f1').click(function(){
var rr = [];
$('.selectpicker :selected').each(function(i, selected){
rr[i] = $(selected).text();
});
alert(rr);
});
OR if you want to using it's valuethen simply write.
或者，如果您想使用它的价值，那么只需编写即可。
$('.selectpicker').val();

You can use as below :
您可以使用如下：
var selectedVal= [];
$('#multiple :selected').each(function(i, selected){
selectedVal[i] = $(selected).text();
alert(selectedVal[i]);
});
