我想使用数组中的值来填充网页。这些值应该替换跨度之间的文本(这已经有效),但同时数组中的某些值应该用作属性并作为文件路径的一部分。最后,只有在值与条件匹配时才应替换某些内容。
以各种方式插入数组数据 - 如何实现?
这是HTML部分:
<p><b><span class="weather">weather here</span></b> and
<span class="temperature">temperature here</span>.</p>
<p><i><span class="color">color here</span></i>.</p>
Here follows is an image loaded according to the data
<img src="fixed_path#weather"></img>. And this should
have the proper <span color="#color">hue</span>.
<span class="warning"></span>
这是jQuery Javascript部分(jsfiddle链接在下面):
var arr = {
"weather": "cloudy",
"color": "#880000",
"temperature": "hot"
};
$.each(arr, function (key, value) {
$('.'+key).replaceWith(value);
// how to replace src path?
// how to replace text attribute?
// make the following conditional
// if($.inArray("temperature.hot", arr) > !=1) {
$('.warning').replaceWith('Warning!');
// }
});
答案 0 :(得分:0)
好的,我已经弄明白了。我了解到我所处理的并不是一个真正的关联数组(它们不像Javascript中的字符串那样存在),而是对象和属性。因此可以使用“objectname.property”选择它们。
这是解决方案(jsFiddle可以在下面找到):
CSS:
.colortext {
color: #00ff00;
}
HTML:
<p><b><span class="weather">weather here</span></b> and
<span class="temperature">temperature here</span>.</p>
<p><i><span class="color">color here</span></i>.</p>
Here follows is an image loaded according to the data
<img src="" class="imagepath"></img>. And this should
have the proper <span class="colortext">hue</span>.
<span class="warning">No extreme weather.</span>
Javascript(jQuery):
var arr = {
"weather": "cloudy",
"color": "#880000",
"temperature": "normal",
"imgagepath": "/path/to/image/"
};
$.each(arr, function (key, value) {
$('.'+key).replaceWith(value);
$('.imagepath').attr('src', arr.imagepath);
$('.colortext').css('color', arr.color);
if (arr.temperature == 'hot') {
$('.warning').replaceWith('Heat warning!');
}
if (arr.temperature == 'cold') {
$('.warning').replaceWith("It's freezing.");
}
});
