尝试使用jquery/php/xml检索Yahoo天气 [英] Trying to retrieve yahoo weather using jquery / php / xml

问题描述

此功能有什么问题?

function yahooWeather(){
    var loadPage = 'yahooweather.php?p='+ $("#myCity").val();
    $("#yahoo").html('<img src="loading.gif" align="absmiddle">');
    $("#yahoo").load(loadPage);
}

还有另一种编写此函数的方法.我不确定它是否能够读取所需的.val，因为我知道它已设置，因为我在上一个函数中使用它来测试它是否已设置，所以我想也许是我的加载调用.

Is there another way to write this function. Im unsure if its able to read the .val required, tho i know it is set as i used it in a previous function to test that it was being set, so im thinking its maybe my load call.

这是页面.通过单击按钮调用此功能后，应获取选择城市"选项设置的值，然后将天气加载到下面的div中.我已经将此CSS设置为绿色，因此我知道它已加载.我也知道我的php脚本就像通过以下操作来对其进行测试一样:

This is the page. This function once called by clicking the button, should get the value set by the "select city" option then load the weather in a div below. I have set the css to this div as green so i know it loads. I also know that my php script works as if i test it by going to the following:

它可以正确地吸引天气.请帮忙！

it pulls the weather in correctly. Please help!

推荐答案

您的问题是，单击按钮时，button元素将重新加载页面.

Your problem is that the button element will reload the page when the button is clicked.

您需要将onclick属性更改为onclick="yahooWeather(); return false;".

You need to change your onclick attribute to onclick="yahooWeather(); return false;".
