regualr expression for extracting all elements

keatskeats Members
edited November -1 in Sahi - Open Source
My html page contains following elements, And there are 40 such elements in the page

<input class="txtTblReslt size33" type="text" maxlength="50" value="P" name="UserDefinedLabelsList.P"/>
<input class="txtTblReslt size33" type="text" maxlength="50" value="C Num" name="UserDefinedLabelsList.C Num"/>

Its actually a text box with pre-defined data in it.
When i want to extract all of those i use regular extraction,


_debug(_textbox(new RegExp(/UserDefinedLabelsList\..*/g)).value);

I was assuming 'g' is for global.
I failed to extract all the label/text and it return me only the first value i.e 'P'

Can someone suggest a solution for this?

Thanks.

    Hi Kirthi,

    APIs in Sahi return you a single element. They do not return a collection. The regular expression based match will also return the first matched element.

    Looking at your snippet, it looks like all these have the same class. You could use
    _textbox("txtTblReslt size33[0]") to _textbox("txtTblReslt size33[39]") to access each of these elements.

    Eg.
    var $values = [];
for (var $i=0; $i<40; $i++){
   _set($values[$i], _textbox("txtTblReslt size33["+$i+"]").value);
}

and then use the $values array.

    You can also use a browser function to collect all necessary values and then use it.
    <browser>
function collectValues(){
   var values = new Array();
   var els = document.getElementsByTagName("INPUT");
   for (var i=0; i<els.length; i++){
     if (els.type == "text" && els.name && els.name.indexOf("UserDefinedLabelsList") == 0){
        values[values.length] = els.value;
     }
   }
}
</browser>

var $values;
_set($values, collectValues());

    The second method is faster than the first.

    Hope that helps.
