1、在元素上同时绑定 oninput 和onporpertychanger事件
例:
1 2 3 4 5 | <script type= "text/JavaScript" > function aa(e){alert( "inputting!!" );} </script> <input type= "text" id= "a" oninput= "aa(event)" onporpertychange= "aa(event)" /> |
2、使用原生js添加监听事件
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | <script type= "text/javascript" > $( function (){ if ( "\v" == "v" ){ //true为IE浏览器,感兴趣的同学可以去搜下,据说是现有最流行的判断浏览器的方法 document.getElementById( "a" ).attachEvent( "onporpertychange" , function (e){ console.log( "inputting!!" ); } } else { document.getElementById( "a" ).addEventListener( "onporpertychange" , function (e){ console.log( "inputting!!" ); } } }); </script> <input type= "text" id= "a" /> |
3、使用jQuery方法绑定事件
1 2 3 4 5 6 7 8 | <script type= "text/javascript" > $( function (){ $( "#a" ).bind( ‘input porpertychange‘ , function (){ console.log( "e" ); }); }); </script> <input type= "text" id= "a" /> |
在监听到 onpropertychange 事件后,可以使用 event 的 propertyName 属性来获取发生变化的属性名称,event.propertyName
实例1:
<input type="text" oninput=" " onpropertychange="" value="Text field" />
实例2:
1 2 3 4 | $( "#name" ).bind( ‘input porpertychange‘ , function (){ var thisTxt=$( "#name" ).val(); $( this ).siblings( "p" ).html(thisTxt) }) |
实例3:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 | //手机号码分段显示 register.phonePropertychange = function () { _this = register; _input = $( this ); var v = $( this ).val(); v = v.replace( new RegExp(/ /g), ‘‘ ); var v1 = v.slice(0,3); var v2 = v.slice(3,7); var v3 = v.slice(7,11); if (v2== ‘‘ ){ _input.focus().val(v1); } else if (v3== ‘‘ ){ _input.focus().val(v1+ ‘ ‘ +v2); } else { _input.focus().val(v1+ ‘ ‘ +v2+ ‘ ‘ +v3); }; //手机号输入完成字体颜色改变 if (v.length === 11) { if (_this.regexpPhone(v)){ _input.css( ‘color‘ , ‘#000‘ ); $( ‘#btnSendCode‘ ).addClass( ‘c-26a949‘ ); _input.blur();; } else { layer.open({content: ‘手机号码不正确,请重新输入‘ ,time: 2, end: function (){ _input.val( ‘‘ ); }}); } } else { _input.css( ‘color‘ , ‘#26a949‘ ); } } //验证手机号 register.regexpPhone = function (phone){ return /^1[3|4|5|7|8]\d{9}$/.test(phone); } |
