假装没事ソ 提交于 2019-12-01 23:35:38
I need to reset all the values ​​of field elements of my page. The elements are: inputs, selects (combobox), checkbox and radio group. Searching found the following code: $("*").attr('value', ''); $("input[type='checkbox']").attr("checked",false); $('select').each(function() { if($(this).children().length > 0) { $($(this).children()[0]).attr('selected', 'selected'); $(this).change(); } }); Inputs and checkbox are ok with this code, but the other components present problems with the codes tested. The radio group needed or take any kind of selection or at least select the first. The combobox

jQuery获取Select选择的Text和Value: 语法解释: 1. $("#select_id").change(function(){//code...}); //为Select添加事件,当选择其中一项时触发 2. var checkText=$("#select_id").find("option:selected").text(); //获取Select选择的Text 3. var checkValue=$("#select_id").val(); //获取Select选择的Value 4. var checkIndex=$("#select_id ").get(0).selectedIndex; //获取Select选择的索引值 5. var maxIndex=$("#select_id option:last").attr("index"); //获取Select最大的索引值 jQuery设置Select选择的Text和Value: 语法解释: 1. $("#select_id ").get(0).selectedIndex=1; //设置Select索引值为1的项选中 2. $("#select_id ").val(4); //设置Select的Value值为4的项选中 3. $("#select_id option[text='jQuery']").attr(

Playing mp3 Shoutcast streams with HTML5 audio in Firefox?

只愿长相守 提交于 2019-12-01 20:47:40
I'm trying to play mp3 shoutcast stream radio stations with HTML5 audio. I don't think it will be relevant but here is the code anyway: var player = new Audio(); player.autobuffer = true; player.src = "http://173.192.48.71:9048/;"; player.volume = 1; player.play(); Shoutcast detects that request comes from browser and returns radio status page, so I put ";" at the end of stream which forces server to return audio stream instead of status page. This works fine in Chrome and Safari, but not in Firefox. Firefox for some reason detects this as text/plain content and refuses to play it with this

jQuery - ensuring all radio groups are checked

自作多情 提交于 2019-12-01 17:37:52
I'd like to loop through multiple (dynamic) radio button groups using jQuery, and if any haven't had a selection made, it throws up an error and stops the form submission. Here's my effort so far: $("form").submit(function() { $(":radio").each(function(){ if($(this).val().length == 0) { alert('Not selected all radios'); return false; } }); }); But it always ignores the if statement which will stop the submission, as if maybe $(this) isn't actually the value of the radio buttons? Here's a jsFiddle: http://jsfiddle.net/aVVW9/ Any help would be much appreciated, thank you! Try this. The approach

几个小问题的总结

独自空忆成欢 提交于 2019-12-01 12:38:40
1.用childNodes获取子元素时如果有空格会视为text文本 总也不用的方法用什么特性都忘记了 2.引入vue.js文件进行页面的开发,在使用封装好的ajax时在其回调函数中不能读取到vue实例的this, 在外面用一个that接受一下this的值就ok了,很简单 3.当vscode的中某父组件无收缩键而其子元素有收缩键,有可能是标签闭合有问题 4.单选radio与label控件配合使用,别忘了label 的for绑定的是radio的id 来源: https://www.cnblogs.com/ybhome/p/11686158.html

Windows Phone 8 device as a Proximity Access Card

隐身守侯 提交于 2019-12-01 12:25:47
Can the NFC hardware within Lumia 920 emulate a 125 kHz Proximity Access Card? It looks like the NFC hardware implements the standard that is a superset of the standard that access cards use. But I don't have enough knowledge of those radio standards to understand if a phone can work only as a receiver or also as a transmitter of such signals. I will also appreciate a link to a good overview article that explains those standards in simpler terms than the official specifications. Currently, card emulation is not supported by the Windows Phone proximity API . Sources: NFC, card emulation NFC
