问题
i get an error in chrome:
Uncaught TypeError: Object s1A has no method 'applyToSelection'
in Firefox(firebug) i get this:
TypeError: val.applyToSelection is not a function
i use the rangy-core and the rangy-cssclassappliere
my Code:
<script type="text/javascript">
window.onload = function() {
rangy.init();
s1A = rangy.createCssClassApplier("css_1", true);
};
//this is the Problem.
function dosome (el) {
var val = el.value;
val.applyToSelection();
}
</script>
<body>
<button value="s1A" onclick="dosome(this);">test</button>
</body>
if id do this:
<script type="text/javascript">
window.onload = function() {
rangy.init();
s1A = rangy.createCssClassApplier("css_1", true);
};
function s1() {
s1A.applyToSelection();
}
</script>
<body>
<button onclick="s1();">test</button>
</body>
it works fine. But i need it for an option field and i want to get the value
回答1:
I suggest storing appliers in an object where each property name corresponds to an input value:
window.onload = function() {
var appliers = {};
rangy.init();
appliers.s1A = rangy.createCssClassApplier("css_1", true);
};
function dosome(el) {
var val = el.value;
appliers[val].applyToSelection();
}
