带类型或值标签的自动点击 [英] Auto Click With Type or Value Tag

问题描述

亲爱的朋友，我有一个网站，我希望为其创建用于自动单击的javascript小书签，但是该网站未使用ID标签.这是网站的代码:-

Dear friends i have site for which i would like to create javascript bookmarklet for autoclick, but the site does not use ID tag. here is the code of site :-

<input type="submit" name="Submit" value="Find Product" 
onclick="return incrementClicksTest('2','true')" class="buttonSubmit">

我使用了此JavaScript小书签

可以很好地使用id，我该如何使用名称，值和类型标记制作小书签

workes fine for id, how do i go about making bookmarklet using name,value and type tag

推荐答案

使用以下内容:

document.getElementsByTagName("input")[0].click();

示例代码: http://jsfiddle.net/dcRsc/

现在，如果您的按钮是页面中的第一个输入，那将起作用.

Now, that will work if your button is the first input in your page.

如果页面中包含许多元素，请使用此选项:

Use this if you have numerous elements in your page:

var elems =document.getElementsByTagName("input");

for(var i=0;i<elems.length;i++)
{
    if(elems[i].type=="submit" && elems[i].name =="Submit")
    {
        elems[i].click();        
        break;
    }
}

示例代码: http://jsfiddle.net/dcRsc/1/

这将触发带有提交名称的提交按钮的click事件.

That will trigger the click event of your submit button, with Submit name.

此外(由于您的按钮已经具有css类)，您可以使用getElementsByClassName()方法:

Furthermore (and since your button already has a css class) you could use the getElementsByClassName() method:

var elems =document.getElementsByClassName("buttonSubmit");

for(var i=0;i<elems.length;i++)
{
    if(elems[i].name =="Submit")
    {
        elems[i].click();        
        break;
    }
}

示例代码: http://jsfiddle.net/dcRsc/2/

这将获得应用buttonSubmit类的所有元素.

That will get all elements with the buttonSubmit class applied.

或

document.getElementsByClassName("buttonSubmit")[0].click();

如果您的按钮是页面上唯一带有该类的元素，则完全避免for循环.

If your button is the only element in the page with that class on it, hence avoiding the for loop altogether.
