After my get request i get
$scope.variables = response.data;
my select is:
<select name="varSelect" id="varSelect" ng-model="wid.adapter">
<option ng-repeat="variable in variables" value="{{variable.id}}">{{variable.name}}</option>
</select>
after that i have two input text fields
<input type="text" ng-model="wid.url" />
<input type="text" ng-model="wid.name" />
On button click i want to post wid
$http.post(some_url, $scope.wid).then(function (response) {
console.log(response);
});
My problem is that i dont get the object variable in wid.adapter. I gog the id.
How to modify my code to get the variable instead of id?
use the variable as the value not the id
and use the ng-option attribute on the select to bind it properly
<select name="varSelect" id="varSelect" ng-model="wid.adapter"
ng-options="variable.name for variable in variables">
</select>

For e.g.
<select class="form-control" id="group_id" name="group_id"
ng-model="form.group_id" ng-options="match_group.id as match_group.name for match_group in match_groups"
required="" ng-change="getGroupWiseMatches()">
....some code
</select>
But match_group instance will have id, name and xyz columns.
Now on the select of match_group, I also want value of xyz column.
How can we get it?
Any help will be appreciated.
Your ng-options expression has the following format: "select as label for value in array".
The select-part is the result that is bound to your ng-model. So if you change your code to the following:
<select class="form-control" id="group_id" name="group_id"
ng-model="form.group"
ng-options="match_group as match_group.name for match_group in match_groups"
required="" ng-change="getGroupWiseMatches()">
....some code
</select>
your variable form.group would contain the entire group object, instead of just the id.
Check this plunker to see it in action
I found the work around for this,
My html will be as it is,
<select class="form-control" id="group_id" name="group_id"
ng-model="form.group_id" ng-options="match_group.id as match_group.name for match_group in match_groups"
required="" ng-change="getGroupWiseMatches()">
....some code
</select>
And in js I am fetching selected entry as,
var found_record = $scope.match_groups.find(obj => obj.id === selected_id);
$scope.form.xyz = found_record.xyz;
I am trying to update two cascading drop down inside a table there are many answers on SO for drop downs, but I was unable to find help on cascading updates inside a Table with dynamically added rows.
Given the many rows they all have varying Id's filter #Id does'nt work. So, How do I identify which rows Dropdown triggered the change & cascade the update another Dropdown/cell in the next col of the same row?
There are 2 DropDownList (select box) inside a table row cell. To simplify this, the first is Country -> Second is state. So a user is expected to select the country and then the state.
My pseudo algorithm:
find which one was fired, and which row (unsure if its needed, should I wire in place)
then fire an ajax call... to get the values based on country
update the second drop down with value in the same table row.
Case 1 Change country and then change state.
Case 2 Just change State, but first get the Country value in the first dropdown of the same row.
I know how to get the change and value in a regular page, but how do I get those changes and update the adjacent dropdown.
$(document).on('change', 'select', function(){
var data = $(this).val();
alert(data);
});
Edit, Stephen request to show HTML
<tr>
<td>
//DropDown 1 (Imagine Country)
<span class="projectcodeid">
<select class="form-control" id="Records_1__TCode_Project_ID" name="Records[1].TCode.Project.ID"><option value=""></option>
<option value="1">Plumbing</option>
<option value="2">Modeling</option>
</select></span>
</td>
<td>
//DropDown 2 (Imagine State)
<input type="hidden" name="Records.Index" value="1">
<input class="timecodeid" name="Records[1].TCode.ID" type="hidden" value="5">
<span class="timecode timecodeDdlId"> <select class="form-control timecodeDdlId" id="Records_1__TCode_ID" name="Records[1].TCode.ID"><option value=""></option>
</select></span>
</td>
<td>
<input name="Records[1].DataRecords[0].ID" type="hidden" value="">
<input class="hours" name="Records[1].DataRecords[0].Work" type="text" value="">
</td>
<td>
<input class="bs-checkbox" name="Records[1].DeleteRow" type="checkbox" value="true"><input name="Records[1].DeleteRow" type="hidden" value="false">
</td>
</tr>
Sample image for clarification
Assuming that you can't identify dropdwns by class or anything.
Assuming that every time you change the value in a dropdown you want to update the other dropdown on the same row.
Assuming that you have only two dropdowns per row:
$('table').on('change', 'select', function() {
var $current_dropdown = $(this),
$other_dropdown = $(this).closest('tr').find('select').not(this);
/// perform any task you need with current and other dropdown
});
You need to give both your <select> elements class names and use relative selectors to select the associated element in the same row.
Assuming your html is
<table id="table"> // give this an id attribute
<tbody>
<tr>
<td><select class="country" ....> ..... </select></td>
<td><select class="state" ....> ..... </select></td>
</tr>
</tbody>
</table>
Then your script will be
$('#table').on('change', '.country', function() {
var selectedValue = $(this).val();
var row = $(this).closest('tr'); // get the row
var stateSelect = row.find('.state'); // get the other select in the same row
// make you ajax call passing the selectedValue to your controller
// in the success callback, update the options of stateSelect
$.ajax({
url: ...
data { id: selectedValue },
....
success: function(data) {
stateSelect.empty();
$.each(data, function(item, index) {
stateSelect.append($('<option></option>').val(iem.ID).text(item.Name));
}
}
});
}

Actually i have a datalist:
<datalist id='modelsList'>
<option value='1'>Dummy1</option>
<option value='2'>Dummy2</option>
</datalist>
This is used in an input:
<input type='text' name='dummy' autocomplete='off' list='modelsList' value=''/>
If i start typing Dummy2 and then i click on the dropdown list result the textbox shows 2. I need to find a way to have 2 as value but Dummy2 as text.
I cannot use a drop-down list (select tag)
Here, my solution as per you want check it out...
You can use input event for achieving such functionality,
HTML
<input type='text' id='dummy' list='modelsList'/>
<datalist id='modelsList'>
<option value='1'>Dummy1</option>
<option value='2'>Dummy2</option>
</datalist>
Jquery
$("#dummy").on('input', function () {
var val = this.value;
if($('#modelsList option').filter(function(){
return this.value === val;
}).length) {
var option = $('#modelsList').find('option[value="' + val + '"]');
$(this).val(option.text());
}
});

The format for a text input in HTML5 is as follows:
<input type="text" name="name" value="Value" placeholder="Placeholder Text">
As a user types in their content, the value changes.
You may be getting confused with textarea:
<textarea name="name">Value</textarea>
If you want to put a textarea tag, you have to know that the value attribute is invalid, but perhaps if you want to use it instead of input, and the format is similar as you put:
<textarea name="name">contentHere</textarea>
i fetch from json and set the value to my angular ionic app. my textbox holds the value. but im unable to get the textbox value to controller. this is how i have done it
controller.js
$http.post("http://www.fooget.com/mydetails.php).success(function(details){
$scope.mydetails= details;
});
and i set the value to my html page
<form>
<div ng-repeat="data in details|limitTo:1">
<p>{{data.f_name}}</p> <!--displays the value-->
<input type="text" ng-model="v.name" value="{{data.f_name}}"/> <!--empty values-->
<input type="text" ng-model="v.id" value="{{data.id}}"/> <!--empty values-->
<button ng-click="push(v)">
</form>
on form click i dont get the textbox values to my controller, im trying to get the vaules to the controller. it doesnt appear
$scope.push= function (v) {
var push_name = v.name; // empty values
var push_id = v.id; // empty values
}
Also in your HTML:
<div ng-repeat="data in details|limitTo:1">
It should be
<div ng-repeat="data in mydetails|limitTo:1">
as you have $scope.mydetails and not details
The real problem is in initializing the values for ng-model:
As you're just setting the value attribute in input text, it's not assigned to the ng-model. Use ng-init directive to set it in the view.
<input type="text" ng-model="v.name" ng-init="v.name=data.f_name"/>
<input type="text" ng-model="v.id" ng-init="v.name=data.id"/>
This will work for you.
I have a form with text boxes and drop down menus. One of the drop down menus is Dependant on the value of another, e.g. InventoryUsage is dependent on the value in InventoryID.
So far I have done the entire site using PHP since I do not know JavaScript, though I found a JavaScript function that can get the value entered in InventoryID, but I cannot use that value in the PHP since PHP is server-side.
What I need to do is change the second dropdown options depending on that of the first dropdown. Then submit the data as I would with a normal form.
Edit:
I used ob_start and included the tpl page and sent all the variables to the page which were pulled from the database prior. All the variables have the same index meaning that InventoryID['0']=ID3456 corresponds to InventoryUsage['0']=60. Therefore when InventoryID is ID3456 i would like to display the Number located at InventoryUsage['0']. I hope this adds some context to the problem.
The index is determined by the php variable $i in my code snippet. The $i would be changed to match the index of the InventoryID field. Say the value of InventoryUsage is 20 then I want to display numbers 1 to 20.
Snippet of code below:
<label>TypeOfSurgery</label> <input type="text" name="TypeOfSurgery" size="35" value="" />
<label>CauseOfSurgery</label> <input type="text" name="CauseOfSurgery" size="35" value="" />
<label>AnaesthesiaUsage</label> <input type="text" name="AnaesthesiaUsage" size="35" value="" />
<label>SurgeryOutcome </label> <input type="text" name="SurgeryOutcome" size="35" value="" />
<label>RecoveryTime</label> <input type="text" name="RecoveryTime" size="35" value="" />
<label>Stages </label> <input type="text" name="Stages" size="35" value="" />
<label>EmployeeName </label> <p>
<select name="EmployeeName">
<option value=""></option>
<?php
for($i=0;!empty($EmployeeName[$i]);$i++)
echo '<option value="">'.$EmployeeName[$i].'</option>';
?>
</select><p>
<label>Cost</label> <input type="text" name="Cost" size="35" value="" />
<label>InventoryID</label> <p>
<select name="InventoryID">
<option value=""></option>
<?php
for($i=0;!empty($InventoryID[$i]);$i++)
echo '<option value="">'.$InventoryID[$i].'</option>';
?>
</select><p>
<label>InventoryUsage </label> <p>
<select name="InventoryUsage">
<option value=""></option>
<script type="text/javascript">
var model= document.getElementById('InventoryUsage');
</script>
<?php
//if inventory in
for($i=0;!empty($InventoryUsage[$i]);$i++)
echo '<option value="">'.$InventoryUsage[$i].'</option>';
?>
</select><p>
In order to populate the InventoryUsage dropdown you need to use JavaScript.
You can use the onChange event for the dropdown InventoryID then fetch the corresponding values via Ajax.
$('#InventoryID').change(function () {
var value =$(this).val(); // selected InventoryID option
//get InventoryUsage values
$.ajax({
method: "POST",
url: "myfile.php",
data: { data: value },
success: function(data){
// Populate new dropdown $("#InventoryUsage")
// this is an example without knowing what is the returned data
var Newoptions = [];
for (var i = 0; i < data.length; i++) {
Newoptions.push('<option value="',
data[i].someValue, '">',
data[i].someName, '</option>');
}
$("#InventoryUsage").html(Newoptions .join(''));
}
});
});
});
then in your PHP file you need to handle the $_POST['data'] , then query your database and return the drop-down options( Arrays ) that will be populated above...
edit :
If you are sure that this index matches the Inventory_Usage and that the InventoryUsage dropdown has previously been populated then
you could try to select the InventoryUsage option using the index of the InventoryID dropdown on change and load events...
try adding this function to you select :
<select name="InventoryID" onChange="set_inventory_usage()"></select>
then add this script to your page's HEAD section..
<head>
<script type="text/javascript">
function set_inventory_usage(){
// Change to getElementById if it is the ID not the name
var Inventory_ID = document.getElementsByName('InventoryID')[0];
var Inventory_Usage = document.getElementsByName('InventoryUsage')[0];
// returns the index of the selected option in the InventoryID dropdown
var InventorySelected = Inventory_ID.selectedIndex ;
// Sets the Usage dropdown to the same index as the Inventory selected option
Inventory_Usage.selectedIndex = InventorySelected ;
}
window.onload = set_inventory_usage ;
</script>
</head>
Option 1: Without JavaScript, the best option is to add an onchange to your first dropdwon list, and when a value is selected submit the form. Since the form is not complete, and only the dropdown value and elements before that are passed, you can set a condition to query the database, get values based on first drop down and reload the form with those options. IThere is nothing wrong with this solution if done properly but to be honest I perfer to do such things with Ajax, hence option 2 below.
Option 2: Learn some JavaScript and use Ajax (Use caution when using other people's scripts in your system)
Edit: Perhaps instead of wring Ajax code from scratch, use jQuery where most things are already done for you. Learning jQuery is very useful if you are going to do web development
