This question already has answers here : Changing the type of an input field using jQuery (text -> password) (5 answers) Closed 6 years ago .

I need some help, and before we get going, I know it is probably not best practice, but I am doing some maintenance to an existing site and need to accomplish the following for a fix. <a rel="lightbox" href="site.com" title="a generated title"> <img src="site.com/img" class="post-image" alt="a long description"/> </a> Okay, so I am trying to figure out how to use jQuery or any other method to take the alt attribute from my image, and dynamically overwrite the title attribute of my a tag. Any help would be awesome, I am kinda lost at this juncture. $(function(){ $("a").each(function(){ $(this)

I have a < div id="thisdiv" class="class1 class2 class3 class4 class5"> text < /div> I need to be able to delete all classes after class3 with jQuery. something like $('#thisdiv').removeClass(all after class3); OR $('#thisdiv').attr('class', all from class1 to class3); Please how can I do that?

How can I check the lenght of the string that is in the attribute?This shows 'undefined' value: var action = $(obj).closest("form").attr('action'); alert(action.lenght); Your spelling is just a bit off, .lenght should be .length : var action = $(obj).closest("form").attr('action'); alert(action.length); Always goto api when some method is not found before you make a post somewhere. http://api.jquery.com http://api.jquery.com/length/ 来源： https://stackoverflow.com/questions/4376276/jquery-length-of-attribute-undefined

prop方法的概况： prop()是jquery1.6中新加了一个方法,用来区分attr方法，专门用来处理DOM属性。一些内置属性的DOM元素或window对象，如果试图将删除该属性，浏览器可能会产生错误，而prop方法则可以避免这种错误发生。换言之，prop可以说是为了处理DOM属性（如 selectedIndex, tagName, nodeName, nodeType, ownerDocument, defaultChecked, 和 defaultSelected）而产生的。 prop的用法： 返回属性的值： $(selector).prop(property) // EXP <input type=‘checkbox’> <button>查看</button> <script> $(“button”).click(function(){ $(“input”).prop(‘checked’); }); //input选中点“查看”返回true //input未选中点“查看”返回false </script> 设置属性和值： $(selector).prop(property,value) // EXP <input type=‘checkbox’> <button>选中</button> <script> $(“button”).click(function(){ $(

I am trying to rotate an image via svg's transform . This is the code I have: <svg width="100" height="100"> <image id="trns" transform="rotate(90,50,50)" width="100" height="100" xlink:href="logo.png"/> </svg> This successfully rotates logo.png by 90 degrees when the page loads. Also, when I change 90 to a different number in firbug's HTML tab the rotation changes accordingly. But when I try to change the value with jQuery, nothing happens: $('#trns').attr('transform', 'rotate(60, 50,50)'); What does firebug do that my attr line does not? Working fine here (with jQuery 1.6.2): http://jsfiddle
