jQuery Mobile-如何设置多项选择的值? [英] JQuery mobile - how to set the values of a multiple select?

问题描述

我在jquery mobile中有多个选择.

I have a multiple select in jquery mobile.

docs: http://jquerymobile.com/demos/1.0a4.1 /docs/forms/forms-selects.html

要获得价值，我就这样做

To get the value I do this

    var leerplandoelen = $("#AddLessonForm_leerplandoelen").val();

        var leerplandoelenString = "";
        if(leerplandoelen != null){
            $.each(leerplandoelen, function(i, le){
                if(i!=leerplandoelen.length-1){
                    leerplandoelenString += "\""+le+"\",";
                }else{
                    leerplandoelenString += "\""+le+"\"";
                }
            });
        }

要获取类似'1"，"2"，"3"'的字符串.

To get a string like this '"1", "2", "3"'.

如何设置值?

我尝试了以下操作:

    $('#AddLessonForm_leerplandoelen').val(['3','6','14']).selectmenu('refresh');

但这没用.

推荐答案

以这种方式进行操作，读取选定项的数组.根据value

Do it this way, read array of selected items. Mark option selected based on value

// array of values
var selected = ["2", "4"];

$.each(selected, function (i, v) {

  // mark options selected
  $("select option[value='" + v + "']").prop("selected", true);

  // refresh selectmenu
  $("select").selectmenu("refresh");

});
