- Clicking buttons and links: iMacros can trigger actions on webpages by clicking specific elements, navigating through different pages, or downloading files.
- **** Editing HTML Elements: This is where iMacros shines, enabling you to modify the content and structure of web pages.
How to Edit HTML Elements with iMacros
iMacros provides several methods to edit HTML elements. Here's a breakdown of some common approaches:
1. Using the "TAG POS=" command:
This command targets specific HTML elements based on their tag name, position, and optional attributes. For example:
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:login_form ATTR=NAME:username CONTENT=your_username
This command will locate the first input field of type "text" within the form with the name "login_form", and having the attribute "name" set to "username". It then sets the content of that field to "your_username".
2. Utilizing the "SET!" command:
The "SET!" command allows you to dynamically modify the content of existing HTML elements.
SET! varUsername your_username
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:login_form ATTR=NAME:username CONTENT={{varUsername}}
In this example, we first define a variable named "varUsername" and assign it the value "your_username". Subsequently, we target the input field using "TAG POS=", and then set its content to the value stored in the "varUsername" variable.
3. Employing "EVAL" for Dynamic Content Manipulation:
The "EVAL" command unlocks more complex manipulation of HTML elements. It allows you to use JavaScript code to dynamically alter the content of elements.
TAG POS=1 TYPE=DIV ATTR=ID:product_price CONTENT=EVAL("var price = document.getElementById('product_price').innerHTML; return price * 1.10;")
This code snippet targets the div element with the ID "product_price", retrieves its existing content, multiplies the price by 1.10 (a 10% increase), and then updates the content of the element with the calculated value.
4. Modifying Attributes:
You can also modify the attributes of HTML elements.
TAG POS=1 TYPE=IMG ATTR=SRC:my_image.jpg CONTENT=my_new_image.jpg
This example changes the source attribute of an image tag, effectively swapping the displayed image.
