js中设置元素class的三种方法小结
<!DOCTYPE HTML> <HTML> <HEAD> <meta charset="utf-8" /> <title>el.className = 'abc'</title> <style type="text/css"> .abc { background: red; } </style> </HEAD> <BODY> <div id="d1">test div</div> <script> var div = document.getElementById('d1'); div.className = 'abc'; </script> </BODY> </HTML>
js="var div = document.getElementById("kw");div.className = "abc";"
driver[0].execute_script(js)
先定位到ID 然后修改这个ID的class属性
//JavaScript属性选择器 选中后用来更改属性值 var a=document.querySelector("div[data-hover-cls=inputs-hover]"); //更改属性值class为“” a.setAttribute("class","")
//注意此方法只适用于ID CLASS TAG之外的子属性的选择
js = "var a=document.querySelector("div[data-hover-cls=inputs-hover]");a.setAttribute("class","inputs J_LaterHover inputs-hover")"
self.driver.execute_script(js)
jiage_mini = "var a=document.querySelector("input[aria-label=价格最小值]");a.setAttribute("value","50")"
self.driver.execute_script(jiage_mini)
jiage_max = "var a=document.querySelector("input[aria-label=价格最大值]");a.setAttribute("value","50")"
self.driver.execute_script(jiage_max)
submit="var a=document.querySelector("button[type=button]"),a.click()"
self.driver.execute_script(submit)
