Style绑定可以通过ViewModel绑定到DOM元素CSS风格属性,例如:
<span data-bind="style: {color: priceColor, fontWeight: priceFontWeight},
text: price"></span>
<script>
var viewModel = kendo.observable({
price: 42,
priceColor: function() {
var price = this.get("price");
if (price <= 42) {
return "#00ff00";
} else {
return "#ff0000";
}
},
priceFontWeight: function() {
var price = this.get("price");
if (price <= 42) {
return "bold";
} else {
return ""; //will reset the font weight to its default value
}
}
});
kendo.bind($("span"), viewModel);
</script>
这个例子显示:
<span style="color: #00ff00; font-weight: bold">42</span>
42
要注意的是CSS属性的名称,如果CSS名称中含有连字符(-),比如font-weight, font-size ,background-color等,在使用时需要省略到连字符,使用camel风格的命名,如fontWeight, fontSize,backgroundColor等。
