Overview when a page is loaded, the first option is selected for a single region in the specified region by default. When a user selects a single region and returns to the page again, you need to select the single-node JS selected last time and specify a radio with the id "admin-content-task"

// The value of the hidden field var platIdVal =$ ("# platIdVal "). val (); // if platIdVal is empty, it indicates that the single if (platIdVal = null | platIdVal = '') option is not checked '') {// the first $ (". admin-content-task input: first "). attr ("checked", true);} else {$ (". admin-content-task input [value = "+ platIdVal +"] "). attr ("checked", true );}
