I think you want to lowercase the checked value? Try: var jIsHasKids = $(‘#chkIsHasKids:checked’).val().toLowerCase(); or you want to check it, then get its value as lowercase: var jIsHasKids = $(‘#chkIsHasKids’).attr(“checked”, true).val().toLowerCase();
If you can, it might be worth using a class attribute on the TD containing the customer ID so you can write: $(‘#mytable tr’).each(function() { var customerId = $(this).find(“.customerIDCell”).html(); }); Essentially this is the same as the other solutions (possibly because I copy-pasted), but has the advantage that you won’t need to change the structure … Read more
You probably want to read up on slice. Your code will look something like this: $(“a”).slice(0,20)
This one has always been a gotcha for me and many others. In short, the opening and closing tags for the <textarea> element must be on the same line, otherwise a newline character occupies it. The placeholder will therefore not be displayed since the input area contains content (a newline character is, technically, valid content). … Read more
If you want a nice slow animation scroll, for any anchor with href=”#bottom” this will scroll you to the bottom: $(“a[href=”#bottom”]”).click(function() { $(“html, body”).animate({ scrollTop: $(document).height() }, “slow”); return false; }); Feel free to change the selector.
Since jQuery 1.5 you can use the deferred objects mechanism: $.post(‘some.php’, {name: ‘John’}) .done(function(msg){ }) .fail(function(xhr, status, error) { // error handling }); Another way is using .ajax: $.ajax({ type: “POST”, url: “some.php”, data: “name=John&location=Boston”, success: function(msg){ alert( “Data Saved: ” + msg ); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(“some error”); } });
Your solution shows the issue here — play is not a jQuery function but a function of the DOM element. You therefore need to call it upon the DOM element. You give an example of how to do this with the native DOM functions. The jQuery equivalent — if you wanted to do this to … Read more
Generally speaking, jQuery plugins are namespaces on the jQuery scope. You could run a simple check to see if the namespace exists: if(jQuery().pluginName) { //run plugin dependent code } dateJs however is not a jQuery plugin. It modifies/extends the javascript date object, and is not added as a jQuery namespace. You could check if the … Read more
Do this: $(document).ready(function(){ $(“.header”).click(function(){ $(this).children(“.children”).toggle(); }); $(“.header a”).click(function(e) { e.stopPropagation(); }); }); If you want to read more on .stopPropagation(), look here.
If you want to restrict input (as opposed to validation), you could work with the key events. something like this: <input type=”text” class=”numbersOnly” value=”” /> And: jQuery(‘.numbersOnly’).keyup(function () { this.value = this.value.replace(/[^0-9\.]/g,”); }); This immediately lets the user know that they can’t enter alpha characters, etc. rather than later during the validation phase. You’ll still … Read more
