The HTML elements are dynamically generated by Ajax, as they are dynamically loaded and displayed in search results. When the user opens the lookup interface, there are system-recommended users, and when the user finds a condition, the results of the lookup are dynamically loaded and displayed. So consider the use of JS to engage. This for loop is to remove an existing form. The new Form object is then dynamically generated based on the data that the AJAX request comes in. Be sure to pay attention to the J variable from large to small loop, otherwise, delete div element will cause serchresultlenth=serchresult.children.length; length change (This problem groped for a long time, just take care, remember)
for (Var j=serchresultlenth-1;j>=0;j--) {var serchchild=document.getelementbyid (serchresult.children[j].id); Serchresult.removechild (serchchild);}
