There’s an easier way that doesn’t require you to go into the options tag: $(“div.id_100 select”).val(“val2”); Check out the this jQuery method. NOTE: The above code does not trigger the change event. You need to call it like this for full compatibility: $(“div.id_100 select”).val(“val2”).change();
//Get var bla = $(‘#txt_name’).val(); //Set $(‘#txt_name’).val(bla);
Edit: Based on your comment below, you would use this: $(‘#one img.’+id) In your question you have a space between img and the .class, I’ve simply removed that so you get img.className or img.’+className With the introduction of template literals in ECMAScript 2015, you can also do $(`#one img.${id}`)
To get all the elements starting with “jander” you should use: $(“[id^=jander]”) To get those that end with “jander” $(“[id$=jander]”) See also the JQuery documentation
Per the jQuery documentation, try this: $(‘input[inputName\\[\\]=someValue]’) [EDIT] However, I’m not sure that’s the right syntax for your selector. You probably want: $(‘input[name=”inputName[]”][value=”someValue”]’)
You can use the jQuery attribute selector: $(‘td[name=”tcol1″]’) // Matches exactly ‘tcol1’ $(‘td[name^=”tcol”]’ ) // Matches those that begin with ‘tcol’ $(‘td[name$=”tcol”]’ ) // Matches those that end with ‘tcol’ $(‘td[name*=”tcol”]’ ) // Matches those that contain ‘tcol’
You can’t manipulate :after, because it’s not technically part of the DOM and therefore is inaccessible by any JavaScript. But you can add a new class with a new :after specified. CSS: .pageMenu .active.changed:after { /* this selector is more specific, so it takes precedence over the other :after */ border-top-width: 22px; border-left-width: 22px; border-right-width: … Read more
It’s a common mistake to create closures in loops in Javascript. You need to have some sort of callback function like this: function createCallback( i ){ return function(){ alert(‘you clicked’ + i); } } $(document).ready(function(){ for(var i = 0; i < 20; i++) { $(‘#question’ + i).click( createCallback( i ) ); } }); Update June … Read more
What I ended up doing for jQuery 1.2 is : jQuery.extend( jQuery.expr[‘:’], { Contains : “jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase())>=0” }); This will extend jquery to have a :Contains selector that is case insensitive, the :contains selector remains unchanged. Edit: For jQuery 1.3 (thanks @user95227) and later you need jQuery.expr[‘:’].Contains = function(a,i,m){ return jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase())>=0; }; Edit: Apparently accessing the … Read more
Why does the :not() selector work in jQuery but fail in CSS? Shouldn’t it work identically in both places since jQuery claims to be “CSS3 Compliant”, or is there something I’m missing? Perhaps it should, but it turns out that it doesn’t: jQuery extends the :not() selector such that you can pass any selector to … Read more
