I’m making a dynamic select menu using Jquery mobile.
First problem that i am facing is that Placeholders are not appearing
for both ie statically created option “–select day–” and “–select time–” which i have statically created in html file. It is just loading the dynamically created values.
Second problem and the Important one is that I want to load “PMtime” if user selects the “Today-Drop”, and “AMtime” if user selects the “Tomorrow-Pick up” option. I created an event handler for it but it seems not working. Please help….
HTML code:
<body onload="init();">
<form method="get" name="datarange">
<div data-role="fieldcontain">
<select id="select-choice-1" name="select-choice-1" class="target" >
<option data-placeholder="true">--Select Day--</option>
</select>
</div>
<div data-role="fieldcontain">
<select id="select-choice-2" name="select-choice-2" >
<option data-placeholder="true">--Select Time--</option>
</select>
<script>
$('.target').change(function(){
var str="";
$("select option:selected".each(function(){
str+=$(this).text() + "";
});
if(str.text=="Today-Drop")
{
check=0;
}
else
{
check=1;
}
Load_selected_time(check);
})
.trigger('change');
</script>
</div>
And in my JS file
var check=0;
var day=[
{name : "Today-Drop",id: "drop"},
{name : "Tomorrow-Pick up",id: "pickup"}];
var PMtime=[
{name : "3:00 PM", id: "3"},
{name : "4:00 PM", id: "4"},
{name : "7:30 PM", id: "730"},
{name : "9:00 PM", id: "9"},
{name : "10:15 PM",id: "1015"},
{name : "11:00 PM",id: "11"}];
var AMtime=[
{name : "12:00 AM", id: "12"},
{name : "1:00 AM" ,id: "1"},
{name : "2:00 AM" ,id: "2"},
{name : "3:00 AM" ,id: "3am"},
{name : "4:00 AM" ,id: "4"},
{name : "5:00 AM" ,id: "5"},
{name : "6:00 AM" ,id: "6"},
{name : "7:00 AM" ,id: "7"},
{name : "8:00 AM" ,id: "4"},
{name : "9:00 AM" ,id: "5"}];
function init(){
Load_selected();}
function Load_selected() {
var arraytoload = day;
var optionlist = '';
var i = 0;
$.each(arraytoload, function (index,item) {
if (i == 0) {
optionlist += '<option selected="' + item.id + '">' + item.name + '</option>';
}
else {
optionlist += '<option value="' + item.id + '">' + item.name + '</option>';
}
i++;
})
optionlist += '';
$("#select-choice-1").html(optionlist).selectmenu('refresh', true);
}
function Load_selected_time(check){
if(check==0){
var arraytoload = PMtime;}
else{
var arraytoload = AMtime;
}
var optionlist = '';
var i = 0;
$.each(arraytoload, function (index,item) {
if (i == 0) {
optionlist += '<option selected="' + item.id + '">' + item.name + '</option>';
}
else {
optionlist += '<option value="' + item.id + '">' + item.name + '</option>';
}
i++;
})
optionlist += '';
$("#select-choice-2").html(optionlist).selectmenu('refresh', true);
}
Your first problem (placeholders not being shown) occurs, because you’re overwriting the content of both .
Try to initialize your ‘optionslist’ string in both functions with
before adding the items to that string in the ‘each’ loop.
