Yes.You can try with some hidden params. $(“#form”).submit( function(eventObj) { $(“<input />”).attr(“type”, “hidden”) .attr(“name”, “something”) .attr(“value”, “something”) .appendTo(“#form”); return true; });
serialize() effectively turns the form values into a valid querystring, as such you can simply append to the string: $.ajax({ type : ‘POST’, url : ‘url’, data : $(‘#form’).serialize() + “&par1=1&par2=2&par3=232” }
You can achieve that by redirecting the form’s action to an invisible <iframe>. It doesn’t require any JavaScript or any other type of scripts. <iframe name=”dummyframe” id=”dummyframe” style=”display: none;”></iframe> <form action=”submitscript.php” target=”dummyframe”> <!– Form body here –> </form>
You could do so by using the attribute accept and adding allowed mime-types to it. But not all browsers do respect that attribute and it could easily be removed via some code inspector. So in either case you need to check the file type on the server side (your second question). Example: <input type=”file” name=”upload” … Read more
Way 1: only works for dataURL, not for other types of url. function dataURLtoFile(dataurl, filename) { var arr = dataurl.split(‘,’), mime = arr[0].match(/:(.*?);/)[1], bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n); while(n–){ u8arr[n] = bstr.charCodeAt(n); } return new File([u8arr], filename, {type:mime}); } //Usage example: var file = dataURLtoFile(‘data:text/plain;base64,aGVsbG8gd29ybGQ=’,’hello.txt’); console.log(file); Way 2: works for … Read more
You could insert input fields without “name” attribute: <input type=”text” id=”in-between” /> Or you could simply remove them once the form is submitted (in jQuery): $(“form”).submit(function() { $(this).children(‘#in-between’).remove(); });
I’ve been using some simple CSS and it seems to remove them and work fine. input[type=number]::-webkit-inner-spin-button, input[type=number]::-webkit-outer-spin-button { -webkit-appearance: none; -moz-appearance: none; appearance: none; margin: 0; } <input type=”number” step=”0.01″/> This tutorial from CSS Tricks explains in detail & also shows how to style them
Two ways. Either create a button and style it so it looks like a link with css, or create a link and use onclick=”this.closest(‘form’).submit();return false;”.
& is HTML for “Start of a character reference”. & is the character reference for “An ampersand”. ¤t; is not a standard character reference and so is an error (browsers may try to perform error recovery but you should not depend on this). If you used a character reference for a real character (e.g. ™) … Read more
I’ve been looking for a lightweight, dependency free dual slider for some time (it seemed crazy to import jQuery just for this) and there don’t seem to be many out there. I ended up modifying @Wildhoney’s code a bit and really like it. function getVals(){ // Get slider values var parent = this.parentNode; var slides … Read more
