以下jQuery代码,不能够实现网页加载完成后弹出消息框的是:()
A: $(document).ready(function(){alert("writeless,domore.");});
B: $(function(){alert("writeless,domore.");});
C: $(functionshow(){alert("writeless,domore.");});
D: $(function(){document.write("writeless,domore.");});
A: $(document).ready(function(){alert("writeless,domore.");});
B: $(function(){alert("writeless,domore.");});
C: $(functionshow(){alert("writeless,domore.");});
D: $(function(){document.write("writeless,domore.");});
举一反三
- 6以下jQuery代码,能够实现网页加载完成后弹出消息框的是:()。 A: <scripttype="text/javascript"> $(document).ready(function( ){ alert("write less, do more."); });</script> B: <scripttype="text/javascript"> $(function( ){ alert("write less, do more."); });</script> C: <scripttype="text/javascript"> $(function show( ){ alert("write less, do more."); }); </script> D: <scripttype="text/javascript"> $(function( ){ document.write("write less, do more."); });</script>
- 执行下面语句 $(document).ready(function() { $(‘#click’).click(function() { alert(‘click one time’); }); $(‘#click’).click(function() { alert(‘click two times’); }); }); 单击按钮,会有什么效果()
- 以下哪段代码不能正确创建函数show()?() A: functionshow(text){alert(text);} B: varshowFun=functionshow(text){alert(text);} C: varshowFun=function(text){alert(text);} D: varshowFun=newfunction("text","alert(text)"};
- 以下jQuery入口函数的写法中,错误的是() A: $(document).ready(function(){}) B: $(function(){}) C: $(document)(function(){}) D: $().ready(function(){})
- 以下哪几种定义函数的方式是正确的? A: function a() { alert(1); } B: function() { alert(1); } C: var a = function() { alert(1); } D: var a = new Function('alert(1);'); E: var a = (function() { return function() { alert(1); }})(); F: var a = function() { return function() { alert(1); }}();
