[英]How to change href of <a> tag on button click through javascript
How to change the href
attribute value of an <a/>
tag through Javascript on button click ?如何在按钮单击时通过 Javascript 更改
<a/>
标记的href
属性值?
<script type="text/javascript">
function f1()
{
document.getElementById("abc").href="xyz.php";
}
</script>
<a href="" id="abc">jhg</a>
<a href="" id="" onclick="f1()">jhhghj</a>
Without having a href
, the click will reload the current page, so you need something like this:没有
href
,点击将重新加载当前页面,所以你需要这样的东西:
<a href="#" onclick="f1()">jhhghj</a>
Or prevent the scroll like this:或者像这样防止滚动:
<a href="#" onclick="f1(); return false;">jhhghj</a>
Or return false
in your f1
function and:或者在你的
f1
函数中return false
并且:
<a href="#" onclick="return f1();">jhhghj</a>
....or, the unobtrusive way: ....或者,不显眼的方式:
<a href="#" id="abc">jhg</a>
<a href="#" id="myLink">jhhghj</a>
<script type="text/javascript">
document.getElementById("myLink").onclick = function() {
document.getElementById("abc").href="xyz.php";
return false;
};
</script>
Exactly what Nick Carver did there but I think it would be best if used the DOM setAttribute method.正是 Nick Carver 在那里所做的,但我认为最好使用 DOM setAttribute 方法。
<script type="text/javascript">
document.getElementById("myLink").onclick = function() {
var link = document.getElementById("abc");
link.setAttribute("href", "xyz.php");
return false;
}
</script>
It's one extra line of code but find it better structure-wise.这是额外的一行代码,但发现它在结构上更好。
remove href
attribute:删除
href
属性:
<a id="" onclick="f1()">jhhghj</a>
if link styles are important then:如果链接样式很重要,那么:
<a href="javascript:void(f1())">jhhghj</a>
<a href="#" id="a" onclick="ChangeHref()">1.Change 2.Go</a>
<script>
function ChangeHref(){
document.getElementById("a").setAttribute("onclick", "location.href='http://religiasatanista.ro'");
}
</script>
Here's my take on it.这是我的看法。 I needed to create a URL by collecting the value from a text box , when the user presses a Submit button.
当用户按下提交按钮时,我需要通过从文本框中收集值来创建 URL。
<html> <body> Hi everyone <p id="result"></p> <textarea cols="40" id="SearchText" rows="2"></textarea> <button onclick="myFunction()" type="button">Submit!</button> <script> function myFunction() { var result = document.getElementById("SearchText").value; document.getElementById("result").innerHTML = result; document.getElementById("abc").href="http://arindam31.pythonanywhere.com/hello/" + result; } </script> <a href="#" id="abc">abc</a> </body> <html>
To have a link dynamically change on clicking it:要在单击时动态更改链接:
<input type="text" id="emailOfBookCustomer" style="direction:RTL;"></input>
<a
onclick="this.href='<%= request.getContextPath() %>/Jahanpay/forwardTo.jsp?handle=<%= handle %>&Email=' + document.getElementById('emailOfBookCustomer').value;" href=''>
A dynamic link
</a>
<script type="text/javascript">
function f1(mHref)
{
document.getElementById("abc").href=mHref;
}
</script>
<a href="" id="abc">jhg</a>
<button onclick="f1("dynamicHref")">Change HREF</button>
Just give the dynamic HREF in Paramters
I know its bit old post.我知道它有点旧的帖子。 Still, it might help some one.
不过,它可能对某些人有所帮助。
Instead of tag,if possible you can this as well.而不是标记,如果可能的话,你也可以这样做。
<script type="text/javascript">
function IsItWorking() {
// Do your stuff here ...
alert("YES, It Works...!!!");
}
</script>
`<asp:HyperLinkID="Link1"NavigateUrl="javascript:IsItWorking();"` `runat="server">IsItWorking?</asp:HyperLink>`
