How to monitor when the body 'data' attribute changes in jQuery?

由 喜你入骨 提交于 2019-12-01 19:45:40
I have data-segment attribute in my body tag that is changed by a slider. I need to trigger a function based on the value of this, when it is changed. I'm not sure how to attach an event listener in this case though? `There is no reliable cross-browser way to receive an event when a DOM node attribute is changed. Some browsers support "DOM mutation events", but you shouldn't rely on them, and you may Google that phrase to learn about the ill-fated history of that technology. If the slider control does not fire a custom event (I would think most modern ones do), then your best bet is to set up

Twitter bootstrap typeahead unable to add to dynamically created element

由 我只是一个虾纸丫 提交于 2019-12-01 19:18:53
Is there a way to convert twitter bootstrap's typeahead function into a $("body").on() function? The following code works fine if the element exists on the page load. $("#job_title").typeahead({ source: searchFunction, onselect: function(obj) { } }); But if I add the text input with id="job_title" dynamically, the above function doesn't work. Is there a workaround for this? Dustin L. This solution requires no additional javascript. From https://stackoverflow.com/a/15094730 $("#element-that-will-contain-typeaheads").on("DOMNodeInserted", function () { $(this).find(".typeahead").typeahead(); });

问题 Is there any way in jQuery to attach a listener to a <td> cell so that when the text inside the cell has changed (by JavaScript, not the user), the event is triggered? 回答1: To extend mway's answer, here is some code. var td = $('#my-table tr td:eq(1)'); var tdHtml = td.html(); setInterval(function() { if (td.html() !== tdHtml) { // it has changed tdHtml = td.html(); } }, 500); ... and for his second suggestion. function updateTd(html) { $('#my-table tr td:eq(1)').html(html); // additional

How to set the input value in a modal dialogue?

由 纵然是瞬间 提交于 2019-12-01 03:29:01
I'm working on 'add a link' functionality. For that I'm using Modal plugin from Twitter Boostrap JS . On the main page there's only the 'link' field to fill, when a user clicks 'add link' button, a modal pops up, and the user sees the complete form to fill 3 fields: link, title, tags. However, I want the link field to be pre-filled with the value from the previous step. It's similar to what happens when you 'save a link' on delicious.com. Thanks to Joe's help ( previous question ) I can print the linkURL on the modal dialogue, but it's important that this linkURL is the value of the link field

Detect if a scroll event is triggered manually in jQuery

由 懵懂的女人 提交于 2019-12-01 03:24:34
This question was already asked here a long time ago: Detect jquery event trigger by user or call by code But it has never been answered conclusively (or maybe I'm simply not able to search properly). Is it possible to detect whether a scroll event has been triggered by the user or by the jQuery animate function? I am trying to prevent the scroll event to trigger itself while doing something like this: $(document).scroll(function(){ $("html").stop(true); var number = 400; //some other stuff is happening here clearTimeout(tout); tout = setTimeout(function(){ if(top == $(document).scrollTop()){

I am counting words in a text field and after a certain amount of words, I use prevent default. In the else, I would like to re-enable the default commands.
