我正在使用 Selenium ＆amp;编写测试脚本的 PHPUnit的即可。
我有一个包含下拉列表的表单。我必须验证是否从数据库中读取数据并将其作为选项显示在＆＃39; select＆＃39;元素。
如果选择中没有选项，则代码为：
<select id="list">
</select>
方法assertNotEmpty("list")不起作用。
有什么想法吗？

`if（document.getElementById（'list'）。innerHTML！==“”）
//做某事` - 可能在资源管理器中不起作用。

您可以使用 int offset = 7; // Maximum range taking effect
float offsetScales[offset+1] = { // +1 is for the zero offset
0.159576912161,
0.147308056121,
...
};
highp vec4 summedColor = vec4(0.0); // We best take a large value now
highp float overallAlpha = 0.0; // The actual end alpha (previously sumOfScales)
highp float overallScale = 0.0; // We need this one so alpha doesn't overflow. If the sum of original scales is 1.0 then this factor is 1.0 and is not needed at all.
vec4 fetchedColor = texture2D(u_texture, v_texCoord);
float scaleWithAlpha = fetchedColor.a * offsetScales[0];
overallScale += offsetScales[0];
summedColor += fetchedColor*scaleWithAlpha;
overallAlpha += scaleWithAlpha;
for(int i=0; i<offset; i++) {
vec4 fetchedColor = texture2D(u_texture, v_blurTexCoords[6-i]);
float scaleWithAlpha = fetchedColor.a * offsetScales[i+1];
overallScale += offsetScales[i+1];
summedColor += fetchedColor*scaleWithAlpha;
overallAlpha += scaleWithAlpha;
fetchedColor = texture2D(u_texture, v_blurTexCoords[7+i]);
scaleWithAlpha = fetchedColor.a * offsetScales[i+1];
overallScale += offsetScales[7+i];
summedColor += fetchedColor*scaleWithAlpha;
overallAlpha += scaleWithAlpha;
}
overallAlpha /= overallScale;
summedColor /= overallAlpha; // TODO: if overallAlpha is 0.0 then discard or use clear color
gl_FragColor = vec4(summedColor.xyz, overallAlpha);
函数获取一系列选项。
selectOptionValues()希望这有助于解决您的问题。
