Hello,
I have HTML-text in a single string which I want to display.
This HTML-text looks similar to this:
"<html><body>" +
"<p>hello world</p>" +
"<p class=default>"+
"<span style="color: #000000; font-size: 17pt; font-family: Verdana">" +
"hello world in special textfont" +
"</span>" +
"<span style="color: #000000; font-size: 17pt; font-family: Verdana">" +
"<i>once again</i>" +
"</span>" +
"</p>" +
"</body></html>";
I cannot use the <text> component to display this HTML-text as the string contains HTML tags which are not supported by the <text> component. (e.g. <span>, <p class=default>)
I actually want to do something similar to the example of chapter 9.4.2 of the OL Developer's guide. I just don't want to set the source of the <html> tag by an explicit HTML-file but by a string of HTML code, which I deliver to the <html> tag.
Is this possible? That would solve my problem.
By the way, I am using DHTML runtime.
Here is a code example of that what I want to do.
<canvas>
<include href="extensions/html.lzx"/>
<class name="browser" extends="window" resizable="true" bgcolor="silver">
<attribute name="htmlContent" type="string" value="" />
<edittext name="txt" text="http://openlaszlo.org/" width="300"/>
<attribute name="htmlText" value="" type="string" />
<button x="310">
Load
<method name="onclick"><![CDATA[
Debug.write("clicked!");
/* by a servlet the attribute 'htmlContent' gets e.g. following content:
this.htmlText = "<html><body>" +
"<p>hello world</p>" +
"<p class=default>"+
"<span style="color: #000000; font-size: 17pt; font-family: Verdana">" +
"hello world in special textfont" +
"</span>" +
"<span style="color: #000000; font-size: 17pt; font-family: Verdana">" +
"<i>once again</i>" +
"</span>" +
"</p>" +
"</body></html>";
*/
this.htmlText = "<html><body>" +
"<p class=default>hello world</p>" +
"</body></html>";
Debug.write("htmltext="+this.htmlText);
//parent.htmlview.setSrc(parent.txt.getText());
parent.htmlview.setSrc(this.htmlText);
parent.htmlview.setAttribute('visible', true);
parent.htmlview.bringToFront();
]]>
</method>
</button>
<html name="htmlview" x="$once{immediateparent.x}" y="$once{immediateparent.y + 25}" width="${immediateparent.width}" height="${immediateparent.height - 25}"/>
</class>
<browser width="500" height="500" x="10" y="10"/>
</canvas>
Kind Regards,
Marc
