问题 This questions targets to Datatables plug-in for JQuery . I need to loop through all table rows (even paginated) and get id of each tr element.

问题 Not sure I'm wording this correctly but here is what I'm trying to do. I am using a function to render multiple instances of wavesurfer on a page. Out of the box this is straight forward, as you just declare each separate instance of wavesurfer : var wavesurfer1 = WaveSurfer.create({ container: domEl, barWidth: 3, ..... var wavesurfer2 = WaveSurfer.create({ container: domEl, barWidth: 3, ..... But I'm preloading JSON stored waveform data and NOT loading any audio file at page load, only when

问题 So i have made an accordion/tabs using jQuery, i use jquery .click method on li elements to turn pages/tabs. Now i wanted to integrate Vue.js to display the JSON data i got from jquery on the accordion pages. But when i add .vue class on the accordion and el: '.vue' , the jquery .click events do not trigger at all, now the tabs wont turn pages. Maybe i shouldn't use Vue with Jquery, but i find jQuery is easier to do a simple task like switching between tabs. PS: im new to Vue 回答1: The event

问题 I have a button as follows: <input type="submit" class="button" value="FooBar" name="FooBar" id="FooBar" disabled="disabled"> I am enabling this button only when certain parameters are met. To test whether it was secure, I pressed F12 (or right click -> Inspect Element) and edited out the text disabled="disabled" . Doing this overrides my code and that is scary. How can I prevent someone from changing it in this manner? I am using php and jquery in this page and using the latter to enable or

问题 I am doing Ajax calls with CORS headers. The short version is that in Firefox, it all works nicely, in Chrome I get an error: "Refused to set unsafe header Access-Control-Request-Method" , and the same thing for Access-Control-Request-Headers. So, I am just confused. Like, very confused. What is it that I have to do in order to make CORS work properly in both Chrome and Firefox? The weird part I will say, though, is that it seems that despite the error, Chrome does execute the Ajax call. I am
