I am getting values from database into a drop down and I have to select one of the options from those.But when i am trying to select any option, the last value of that drop down list is getting selected automatically. i am using Angular js to bind the UI with database.
before selection : I was trying to select the second path from the drop down but the third path is getting selected automatically.

I have a dropdown with 4 options. I want these options to be prepopulated depending on value that is selected from a different field. The different field is a "countries" field.
If country "A" or country "b" is selected, I want the dropdown to populate option 1.
If a different country, populate option 2.
Thanks in advance
You can try the following:
Find which event is fired when a user change the first dropdown value
Register a function to this event
In this function, detect what is the new input from the first dropdown. Check it, and change the value of the second dropdown depending on this check (How do I programmatically set the value of a select box element using JavaScript? could be useful for the implementation)
If you have issue trying to do it, do not hesitate to ask :)
I have one bind-able property which I have to use in drop-down to analyze which ID is selected.
I am using change.call method to identify when user will select drop-down options then console will give selected id.
On options selections change.call is giving random ID on same option .
I have two combo boxes in a form. The 1st combo box: type of position hiring while the 2nd combo box: location. The values of two combo boxes are dynamically populated from mysql
I need to change the value of 2nd combo box. If the value of 1st combo box change to "Linux Admin", the value of 2nd combo box should display the designated locations depends on the value of 1st combo box.
I found with the same function, but the values are manually populated Javascript - combobox change value of other combobox
I've solved this before. I did this in an MVC C# application, but the idea would still work here.
When you are building your HTML, create the name-value pairs for the combo boxes with the Name (in one of your stated cases) as being 'Linux Admin'. In the value for that, put all the locations in as a tab-delimited string.
In the javascript, when the first combo box changes, have the script read the values from the first combobox selector and split those values and put them in the next combo box as the names.
Here is a general idea that I used for a set of select boxes to allow for the selection of a Make, and then the next select box be populated with the available models.
<select>
<option value="Escape,Expedition,Explorer,F150,F350SD,Focus,Fusion,Mustang,T250 Vans">Ford</option>
<option value="Acadia,Envoy XL,Sierra 1500,Sierra 2500 Clsc,Terrain,Yukon">GMC</option>
</select>
I am trying to retrieve data table cell values to input and select option boxes. The values are displaying in the input box but it fails to display in option select box.
$("#txt_UserName").val(table.cell('.row-modified', 3).data());
$("#dd_Country").select2(“val”, table.cell('.row-modified', 2).data());
Selects don't have value properties. You need to find the matching option element underneath the select and set its selected property (while ensuring all other options do not have selected set).
I have a select element in HTML. I save just selected value in DB. When I want to edit this element in users side , I need to show value that selected before. I see this link. but in this link user himself determines default value,while I want to have an editable select element.
I should first retrieve selected value from DB , then set it as default value to my select element. how can I do it in JavaScript?
