如何通过Selenium获取ExtJS组合框的选定值？

Question

我有一个网页渲染使用extjs。它用一些生成的ID呈现多个组合框。和每个组合框都选择了不同的选项。我怎样才能找出在每个组合中选择了哪个值？

在调试HTML DOM时，我观察到ExtJS呈现DIV是不同的，可选择的选项在最后呈现在不同的DIV中。因此，我无法定义任何XPath来找出所选值。

<div class="guide-bg" id="sample"><table>
    <tr><td id="row1"> </td></tr>
    <tr><td id="row2"></td></tr>
</table></div>

<script>
Ext.namespace('Ext.exampledata');
Ext.exampledata.states = [['Alabama'],[ 'Alaska'],['Arizona']];

var store1 = new Ext.data.SimpleStore({
    fields: [ 'state'],
    data : Ext.exampledata.states
});

var combo1 = new Ext.form.ComboBox({
        store: store1, displayField:'state', typeAhead: true,
        mode: 'local', forceSelection: true, triggerAction: 'all',
        emptyText:'Select...', selectOnFocus:true, renderTo: 'row1'
});

var combo2 = new Ext.form.ComboBox({
        store: store1, displayField:'state', typeAhead: true,
        mode: 'local', forceSelection: true, triggerAction: 'all',
        emptyText:'Select...', selectOnFocus:true, renderTo: 'row2'
});
</script>

<div class="guide-bg" id="sample">
  <table>
    <tbody><tr><td id="row1"> 
    <div class="x-form-field-wrap x-form-field-trigger-wrap" id="ext-gen148" style="width: 206px;">
        <input type="text" name="ext-comp-1028" id="ext-comp-1028" autocomplete="off" size="24" class="x-form-text x-form-field x-form-empty-field" style="width: 181px;">
        <img class="x-form-trigger x-form-arrow-trigger" src="sp.gif" id="ext-gen149">
    </div></td></tr>
    <tr><td id="row2">
    <div class="x-form-field-wrap x-form-field-trigger-wrap" id="ext-gen150" style="width: 206px;">
        <input type="text" name="ext-comp-1029" id="ext-comp-1029" autocomplete="off" size="24" class="x-form-text x-form-field x-form-empty-field" style="width: 181px;">
        <img class="x-form-trigger x-form-arrow-trigger" src="sp.gif" id="ext-gen151">
    </div></td></tr>
  </tbody></table>
</div>  

<div class="x-layer x-combo-list " id="ext-gen146" style="position: absolute; z-index: 12005; visibility: hidden; 
    left: -10000px; top: -10000px; width: 204px; height: 129px; font-size: 12px;">
    <div class="x-combo-list-inner" id="ext-gen147" style="width: 204px; height: 129px;">
        <div class="x-combo-list-item x-combo-selected">Alabama</div>
        <div class="x-combo-list-item">Alaska</div>
        <div class="x-combo-list-item">Arizona</div>
    </div>
</div>

使用selenium的Eexecute JS（如何将JavaScript与selenium WebDriver Java一起使用）。在js中，您可以使用“ext.componentQuery.query('combo')[0].value”代码获取combo值
