button onclick

The a tag is mainly used for page Jump. It can be implemented through the href attribute or in The onclick event. Blog This code is fine in mainstream browsers, but cannot be redirected in IE6. What is the reason? Javascript: void (0 ); Void (arg); can be understood as a function that returns null forever, but its parameter cannot be null. Its parameters can be any expressions or even functions. Test IE6 first runs the events bound to the DO

During web page development, we often encounter the following situations:1. A tag is only used to trigger the onclick action;2. Show the pointer with the mouse or other visual effects similar to the label.For example, to avoid misoperation during the delete operation, a dialog box is displayed asking the user to determine whether to delete the operation. Therefore, we often use the link The Code is as follows:Copy codeThe Code is as follows: The conse

The following code is problematic:divclass="left_btn" onclick="deletePlan("12");"id="delete_btn">删除该设置div>Should be changed to:divclass="left_btn" onclick="deletePlan(‘12‘);"id="delete_btn">删除该设置div>The general "12" or "12" is generated in the background scripting language, and generally does not notice whether the "" in the HTML tag attribute is conflicting, so the problem is very easy to see.

In the background management of a blog, you can add an address for a category, but it is difficult to add an onclick event. If you want to pass the current object to a function, you can write the URL as "Javascript: shoControlSidebar (this)". However, the result shows that this is not feasible. The previous parameter passed is an object, however, no other information is available. I want to get innerText, but this does not point to its A tag.This is d

object.The reason is the event binding method.Onclick = "foo ()" means to directly execute the foo () function without any parameters,In this case, firefox has no chance to pass any parameters to foo.In the case of btn. onclick = foo, firefox has the opportunity to pass parameters to foo because it does not directly execute the function.Solution:Method 1: This is a stupid method. Since firefox does not have the opportunity to pass parameters, it is e

When you develop Web pages, we often experience the following situations:1. A label is only to trigger the onclick behavior;2. Performance should have the mouse pointer pointer display, or other similar to a label visual effects.For example, in order to avoid misoperation when performing a delete operation, we will pop up a dialog box to let the user know whether to delete it or not. Therefore, we often use links The code is as follows: Copy Code c

All right, just put some JS code on it. var js = "alert (' B: ' + this.id);" return false; "; var Newclick = eval ("(function () {" +js+ "});" ; $ ("#anchor"). attr (' onclick ', '). Click (Newclick); If the onclick event has a value, empty first, then click (eval () {...}) assigning values $ ("Input[name= ' Ordercar ']"). attr (' onclick ', '). Cl

A label is mainly used to achieve page jump, can be achieved through the HREF attribute, can also be implemented in the OnClick event.The code is as follows: This code in the mainstream browser is no problem, but under the IE6 will be unable to jump the problem. What is the reason for this?The code is as follows: Javascript:void (0); void (ARG), which can be interpreted as a function that returns null forever, but whose arguments cannot be null. Its a

for this is how the event is bound Onclick= "foo ()" is executed directly, the Foo () function, without any arguments, In this case Firefox has no chance to pass any arguments to Foo And Btn.onclick=foo this case, because instead of directly executing the function, Firefox has the opportunity to pass parameters to Foo Workaround: Method One: The more stupid method, since Firefox does not have the opportunity to pass the parameter, then oneself dilige

The simplest is this: Dynamically adding onclick events: If you use the anonymous function function () {}, the following are shown: The above method is actually the same principle, are the values that define the OnClick property. It is important to note that if you define Obj.onclick multiple times, for example: OBJ.ONCLICK=METHOD1; OBJ.ONCLICK=METHOD2; OBJ.ONCLICK=

javascript:void (0) simply represents a dead link with no information. So it's best to use void when calling scripts (0)href generally refers to a URL address, you can also call JavaScript, such as href= "javascript:xxx ();", recommended in the documentation: try not to use JavaScript: protocol as the href attribute of a , This will not only lead to unnecessary triggering of window.onbeforeunload events, in IE will make GIF animated pictures stop playing.We know that the

0 reply content: reasonable guess: when assigning an internal operation to onclick, remove the original one and add the new one. Pass This is not necessarily the result of different browsers. The underlying code is definitely not Javascript I only went to the machine and read the oldest blink code a few years ago. EventListenerMap depends on EventListenerVector. This is a Vector. Typedef Vector In this case When
