1. For example, there is such an element
"a href=" javascript:; "ng-click=" actions.routerDetail.open (router) "class=" ng-binding "share_router" / a "/ h3 >
now there is a requirement, that is, when the value of the tag is dynamically defined by the user, such as the share_router above,
how to locate yourself through the value of share_router, and then click with the mouse? In other words, what do you write when I click Element?
