ajax

问题 hi I want to build a control panel for a web art application that needs to run in fullscreen, so all this panel, that controls stuff like colors and speed values, have to be located at a different window. My idea is to have a database storing all these values and when I make a change in the control panel window the corresponding variable in the application window gets updated too. So, it's basically a real-time update that I could do with AJAX setting a interval to keep checking for changes

问题 I'm having a problem with my fetch() call not working correctly. I have a recursion method that calls itself within this function, but once it passes the if statement, the data itself is not being resolved to the .then() call below. I would like to keep the recursion method within this function. Because the system that this function is calling will change the data.result to a different result that is not null. I just don't know when that will happen, hence that is why I'm using the recursion

问题 I need to implement synchronous Ajax calling mechanism. I already implement ajax calling function in my helper same as below : MH.helper = { ajax : function (option) { if(option !== undefined) { for(var opt in option) { this[opt] = option[opt]; } } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari this.xhr=new XMLHttpRequest(); } else { // code for IE6, IE5 this.xhr=new ActiveXObject("Microsoft.XMLHTTP"); } } } I also implement Ajax prototype as same as below : MH
