$('.issuing_country option[text="Japan"]').prop('selected', true);

Best How To :

You shouldn't be trying to set anything like that using jQuery when using knockout - instead, do it all on the viewmodel.

Your <select> options are bound to your issuingCountries observableArray, and the value selected is bound to your IssuingcountrySelected observable. To select an option automatically, just set the property on your viewmodel, and knockout will take care of the rest:

//Assuming "Japan" is at index 2:
vm.IssuingcountrySelected(vm.issuingCountries()[2]);

If all you know is the name of the option you want to select, first you must find the right item, so you'd need a function for that:

function findCountryByName(name) {
    for (var x = 0; x < vm.issuingCountries().length; x++) {
        if (vm.issuingCountries()[x].Country == name)
            return vm.issuingCountries()[x];
    }
    return null;
}
vm.IssuingcountrySelected(findCountryByName("Japan"));

Binding Checkbox to td element

javascript,jquery,html

Since you are adding checkbox dynamically to the table you can attach clickevent to it as below: While you prepend add one more property called class to checkbox $(".sth:nth-child(5)").prepend('<input type="checkbox" class="chkadd" name="mailcheck" id="cbe">'); Adding change event to dynamically added checkbox $(document).on('change','.chkadd',function(){ //do required stuffs here }); instead of $(document) you...

Get info from dynamic/growing form

Something like this?

add value to existing class in jQuery

javascript,jquery,html,css

Use attr() like $(document).ready(function() { $('.project-open').hide(); $('.hackandfly, .scanergy, .connecting-food').click(function() { $slidah = $($(this).attr('class')+'-open'); $slidah.slideToggle(); $('div.project-open').not($slidah).slideUp(); }); }); However, the above will fail if you have multiple classes. A workaround would be to add data-* to the clicked elements like <div class="hackandfly other-class" data-class-target="hackandfly-open"></div> and then $(document).ready(function() { $('.project-open').hide();...

Dynamically select from a dynamically generated dropdown
