In-Depth Information
You can also use the + symbol to combine a variable with a text string and then write
the combined text string to the document. The following statements use the libName
variable and the ƒdocument.write() method to write the text string <p>Welcome to the
Monroe Library</p> to the Web document:
You can use the document.write() method with the variables you've already created
to write the hypertext link for Catherine Adler's e-mail address. The code is as follows:
If the text string is stored in the emLink variable, these commands
will write the following HTML to the Web page:
Notice that the document.write() method nests single quotes within double quotes
so that the HTML code written to the Web page places the value of the href attribute
within a set of single quotation marks. You'll add this JavaScript code to the Web page
now, replacing the previous commands.
To replace the document.write() commands in the script:
1. Return to the mpl.htm file in your text editor.
2. Replace the three document.write() statements in the script with the following
code, as shown in Figure 10-15:
Make sure that you
enclose single quotes
within a set of double
quotes so that the single
quotes appear in the
rendered HTML code.
document.write(“<aƒhref= ' mailto:”ƒ+ƒemLinkƒ+ƒ“ ' >”);

3. Save your changes to the file and then reload mpl.htm in your Web browser. The
hypertext link for Catherine Adler's e-mail address should remain unchanged
from what was shown earlier in Figure 10-11.
