I have a quick question. I am wanting to retrieve a value from my sqlite table (a specific value from a row in a specific column) and I was wondering how to get that value and put it back into a selectmenu.
$('#items option:selected').val(row['column1']);
This is what I have so far in my select statement for sqlite. The #items is the id of my selectmenu, and val.(row['column1']) is the value that I want to get to put it inside the selectmenu specified if that makes sense.
I should note that I have successfully done this for all the form data, the values are being retrieved and displayed correctly, it's just the selectmenu that isn't displaying the required value. Thanks
Got it working, changed to:
$('#items').val(row['column1']);
then added this after the for loop in the sqlite statement:
$('#items').selectmenu('refresh', true);
This correctly displayed the value from the table.

i'm using the PDO library in php to access a database and return some values into a table which need to be shown when the user first opens the webpage,
after this I want to implement a filter option, so that the user can input some data in a form field and the data shown is updated according to the filters set by the user.
I don't know how to update the DOM in this case, would it be possible to update the DOM using Jquery so that only the new values are shown in the table, or do i need to redirect to a new page/reconstruct my table with a full request/response cycle.
thank you for your help in anycase.
If I understand correctly, you want to output the data from the result of your MySQL query as a table, and then having a search bar which will filter the output table according to the search bar. What I would do is first use the data to generate a table and give it a css class. For the search bar you can use form or event listener to process apply your filter from the value in the search bar. For example you can loop the rows of the table and check if a column contain a substring of the search bar value(as an example, check with whatever criteria you prefer) and just add a css value display: hidden to the row, or restructure the table, there are many ways of doing it.
I'm been using this link. The issue is when I'm done submitting and filling those dropdown it reloads, When I come back again the previous value will gone. I just want to remain those value in dropdown but I think there is a conflict when using that link above. It also didn't display the other value of dropdown. All I know I should use localStorage. Is there any expert can give me directions and ideas for this?
Setting the value of dropdown when I click search/submit button
var values = document.getElementById('province').value;
localStorage.setItem("prov", values);
getting the value of province dropdown
document.getElementById("province").innerHTML = localStorage.getItem("prov");
It is possible to apply this through that link I provided?
Firstly, make an object that you can read from with mental ease.. something like
var obj={province:provinceElement.value, municipality:Municipality.value, ...etc}
then when you save all your values to the object, save it with a key("whatever it is once it's a key only your code uses")
localStorage.setItem("uniqueKeyOnlyMyCodeUses",JSON.stringify(obj))
Then you can get all your data like
var localObj=JSON.parse(localStorage.getItem("uniqueKeyOnlyMyCodeUses"))
localObj would have all the data you saved in just one key and objects are a very easy way to play around with the data you gave
I created the links in the left-most column to target a JavaScript function and I can successfully pass through the value of the row ID to that function.
Once clicked, a modal pops up to present a form to update the fields. However, I need the fields in the modal to be populated with the information from the row clicked. I figured I could create a hidden page item (P2_SONG_SELECT) to store the row ID so that I can use the value in my query for the data. My problem is I haven't been able to assign the row ID value to the application item.
Here is my JavaScript:
Each 'Edit' button successfully uses this URL target:
javascript:viewEditSong$(#Row_ID#).val();
to call this function:
function viewEditSong(Row_ID) {
alert(Row_ID); // successfully alerts the Row ID
$("#P2_SONG_SELECT").val() = UA_ID; // fails to assign
$("#EditSongWindow").dialog('open'); // open the modal
}
How do I properly assign the page item the value passed in?
Elsewhere I use simliar syntax effectively:
ajaxRequest.add("P2_FILE_MAIN", $("#P2_FILE_MAIN").val()); // this works fine
By 'application item' I presume you meant 'page item' as per your question title, since you're prefixing with page number.
Use this to set a value on the browser.
$s('P2_SONG_SELECT', 'xyz')

Scott's post effectively solves your problem by using the built in APEX set method, but as an aside, you are attempting to use the jQuery val() method in the wrong way.
Instead of:
$("#P2_SONG_SELECT").val() = UA_ID;
You should use:
$("#P2_SONG_SELECT").val(UA_ID);
Have a look at the documentation for val().
http://api.jquery.com/val/#val2
You can see that the usage of the function differs depending on whether you want to set or retrieve a value.
It would be little complicated. Suppose I have a select list with items as status.I select a status and do some modification in the page, when I change to different status all the modificatiions which I did for previous selected status should be saved and send to a servlet. I was trying to do using change() , but it was taking current select field. and Also page relaods when status from the select is is changed thats y all the previous selected fields value also get lost.
Do anyone have ides of how to do it using jquery/Javascript as if I get the value I can pass to the servlet.
Basically I work on component based java using Apache Click framework. If some can relate with that too it would be great help too.
basically you need to store the previous value yourself and keep track of it, something like that:
var $selectElement = $("#selectElement");
$selectElement.change(function () {
var previousValue = $selectElement.data("previous");
//do something with previous value
$selectElement.data("previous",
$selectElement.find("option:selected").val);
}).change();
a quick example http://jsfiddle.net/dCkwd/
Try storing the values in a cookie with the jQuery $.cookie plugin and updating the cookie on change(). You can then access the latest cookie value.
I hope this helps!
I have a table with a bunch of rows. In the last column of every row, there is a dropdown. When the dropdown changes, I need a new table row to appear below the row where the user selected the dropdown item. However, I also need the new row to have different data depending on what was selected in the dropdown.
Is any of this possible using only jQuery?
Note that I'm using ASP.NET for back-end development, so if a solution can be found without using ID's that would be great.
$("table select").live("click",function(){
var row=$(this).parent().parent();//add some .parent() untill you get the TR element
var val=$(this).val(); //<select> value if you want to use it for some conditions
$("<tr><td>....</td></tr>").insertAfter(row);
})
It's simple enough to add the HTML using JQuery. However, if you intend to save this data back to the server, the default ASP.NET process (using ViewState) will ignore the new rows. Instead, you would need to directly read the submitted form properties.
