I read this site: https://www.dmcinfo.com/latest-thinking/blog/id/8567/siemens-s7-1200-web-server-tutorial--from-getting-started-to-html5-user-defined-pages to make html web page without post_back. so i did this rule: 1. In order to update PLC tags without experiencing the post-back, we can use some JavaScript to update the value in the background. First we need to create another HTML file and move our tag reference to it. 2. In order to illustrate this, create a new variable in the "webdata" DB called triangleWave. Next create a new file called "IOtriangleWave.htm" that looks like this: "IOtriangleWave.htm" :="webdata".triangleWave: 3. Now the "index.htm" as follows: <!-- AWP_In_Variable Name='"webdata".triangleWave' --> <!DOCTYPE html> < html lang = "en" > < head > < meta charset = "utf-8" > < title >Javascript Example</ title > < script src = "jquery-2.0.2.min.js" ></ script > </ head > < body > <!--This label value is being updated in the background using JavaScript--> < label id = "triangleWave" name = "triangleWave" >:="webdata".triangleWave:</ label > </ br > < input id = 'setvar' type = "text" /> <!--This button modifies the value in the background using JavaScript without a postback--> < button >Modify</ button > < p >< img src = "logo-DMC.png" alt = "DMC Logo" >< p /> </ body > < script type = "text/javascript" > $(document).ready(function(){ //query the trianglewave variable every second $.ajaxSetup({ cache: false }); setInterval(function() { $.get("IOtriangleWave.htm", function(result){ $('#triangleWave').text(result); }); },1000); }); </ script > </ html > I want to add more "reading variable" to my program and use update PLC tags without experiencing the post-back. what should i do? |
